c60f5e01dc Re-anchor a moving reel on where it is, not what it was playing 
A viewport change re-anchors the reel on the video that is playing,
resolved by id rather than by a scroll position the change has already
invalidated. That is what keeps a rotation on the same video.

Mid-swipe it names the wrong one. setActive runs from onScroll's next
frame, so a resize landing before that frame still reads the video being
swiped *away from* -- and realignToActive writes its position straight to
scrollTop, hauling the reel back to it. A phone slides its chrome on every
scroll, so the resize lands mid-swipe on nearly every swipe: the reel went
where the thumb put it, far enough to show the top of the next video at
the bottom of the screen, and was then written back a beat later.

The input guard in onScroll could not catch this. There is no scroll event
to guard -- the write happens inside the resize.

So while the reader is demonstrably driving, take the reel's own position
as the authority and re-anchor on the step it is nearest at the new
height. It still lands on a snap point, so nothing is left straddling two
screens, but the swipe stands. Only a step's worth of disagreement counts
as theirs: a scroller just re-parented into or out of the
picture-in-picture window reads 0, and following that would land them on
the first video instead of their own.

7033288bc4 Hold the slides for the whole turn, not until it first pauses 
The slides are held at the size a turn is heading for so the picture steps
once, straight into the shape it keeps, instead of being re-letterboxed
through every shape the viewport passes on its way round.

The hold came off once the height had gone six frames unchanged, which
stood in for "the viewport has stopped moving". It does not: a turn
arrives in steps, and the gap between two of them is routinely longer
than six frames -- on a phone and in a loaded tab alike. So the pin came
off mid-turn, the slides took an intermediate shape, and the picture
jumped twice on the way round. That is the stutter the pin exists to
remove, and TURN_HOLD_FRAMES was meant to be "long enough that a viewport
animating round in steps is not mistaken for one that has arrived" -- six
frames is not.

The device does say when a turn is underway, so believe it: while the
announcement stands the pin holds, and the frame count is left to end the
pins nothing announced, where there is no signal to go on and no turn to
ruin. The realign window has to stop concluding mid-turn too, since
closing it releases the pin by the other door; SETTLE_MAX_MS outlasts the
announcement and still guarantees both of them end.

The cost is that an announced turn keeps the old size until the
announcement lapses rather than letting go the moment the viewport looks
still. That buys the one step.

872786a657 Let a swipe count while the viewport is still moving 
A viewport change opens a window in which the feed holds the reader's
video in place, because the scroll-snap container re-anchors on positions
measured against the height from before it and must not be allowed to
flip the video. The window answered every scroll it saw with a realign.

On a phone that is the worst moment to do it: the chrome sliding out of
the way is caused by the swipe, so the window stood open at exactly the
moment the reader was swiping. The reel moved under the finger, far
enough to show the top of the next video at the bottom of the screen, and
was then pulled back to where it started -- a second later, once the
settle window ran out.

A re-anchor has nothing behind it and a swipe has a finger or a wheel, so
record the input and let a scroll that follows one close the window
instead of being reverted into it. Closing it that way skips the realign,
or the close would undo the swipe that caused it. Only input that means
to scroll counts -- a finger that has moved rather than one that has
merely landed, since a tap must not sign for the re-anchor after it.

Telling a turn apart from the chrome moving was reading the orientation
flip alone, which a few pixels of height cross whenever the viewport is
near enough to square. That pinned the slides and turned snapping off for
a second over a height change, which is the one thing it is there to tell
a turn apart from; a turn swaps the long side, and swapping it moves the
width too.

7fc718158a Check a direct route hands back the video it was asked for 
The proxy exists to get around CORS, hotlink protection and TLS
fingerprinting, so the player probes whether a CDN will serve the browser
itself and skips the hop when it will. The probe took a readable status
line and some bytes as proof.

Not every hotlink guard refuses a foreign Referer with a 403. eporner's
CDN answers one with a 302 to a one-minute "watch this at our site
instead" clip, served 206 with Access-Control-Allow-Origin: *. fetch()
follows that redirect without comment, so the probe read the stand-in as
a win, cached the host as direct, and the player restarted playback on
the raw URL -- where the browser sent the page's own Referer again and
got the stand-in a second time. An eporner video played as 61 seconds of
advertisement instead of itself.

Only the resolved path was affected: yt-dlp's eporner formats carry no
Referer, so refererRequired was false and the race ran. The listing's own
formats name one and were always proxied.

So ask the proxy, which carries the Referer the origin wants, how long
the media is, and refuse a direct route that reports another length. The
question goes out alongside the direct fetch rather than after it, and an
unknown length on either side leaves the old bytes test standing, so
chunked responses and playlists decide as before. No Range header: that
would cost a CORS preflight.

4f772773e1 Let the reader have the captured pictures taken again 
A frame taken out of a video is kept for good: that is what makes a dead
favorite cheap to scroll past, and it is also the one thing that can go wrong
with no way out. A picture from the wrong moment, or one kept by a version of
this that would keep a frame with nothing in it, stays on the card for the life
of the item.

So Settings grows a Captured Thumbnails section: what is kept and how much room
it takes, and a button that throws the lot away. The cards on screen go back to
the start of the thumbnail ladder rather than waiting to be scrolled out of the
window and back, which is where a fresh capture comes from, and the session's
memory of which items there was no point asking about goes with the pictures --
otherwise "take them again" would quietly skip every item that failed once.

be058dba37 Keep a captured thumbnail only if there is a picture in it 
A favorite whose thumbnail is gone gets a frame out of the video instead. The
one this came from got a black box: 1.6 KB of pure black, kept for good, on an
item whose video is black nowhere -- ffmpeg puts its opening frame at YAVG 185
and its quarter mark at 130.

So that was not a frame of the video at all. Drawing a video element that has
not presented a frame gives back the canvas untouched, and transparent black
JPEGs as pure black at about 1.6 KB -- comfortably past the only test a capture
had to pass, which was being over 512 bytes long. Nothing then asked whether
the picture had anything in it, and the cache exists precisely so that nothing
asks again.

The frame now has to be a picture of something, and both ways it can fail to be
one have the same answer: take it somewhere else. The brightest sample in the
drawn frame decides -- an untouched canvas has no painted pixels at all, and a
frame that genuinely is black (a lead-in, a fade, a cut) is no better a
thumbnail than one of nothing. A blank frame moves on: the quarter mark again
with the element playing, since an element that is playing has to present
frames while a seeked one does not, and then the half mark. The frame is taken
on `requestVideoFrameCallback` where there is one -- the browser saying a frame
is on screen now -- rather than on `seeked` alone, which Chromium backs with a
decoded frame but Safari does not for an element that is off-screen and paused.

Nobody will say how long this item is (the extractor reports no duration and
the favorite kept a zero), and a clip with no length had no quarter mark to
seek to, so the capture settled for the first frame the element decoded -- the
opening one, which is the frame most likely to be black. It now seeks blind to
a fixed mark, clamped back into the file if that is past the end.

And the black pictures already kept heal: an index entry carries a marker
saying its picture was checked, every capture writes one, and an entry without
one is measured once -- behind the picture the card has already painted -- then
dropped and taken again if it turns out to be a frame of nothing.

6dac1028a3 Take a thumbnail out of the video when the listed one is gone 
A favorite outlives its thumbnail. Sources sign their CDN paths and the
signature expires, so a video kept months ago has a `thumb` that 404s and
a card that is a grey box with a title under it. Asking the source page
for a fresh picture covers the case where the page still exists; nothing
covered the case where it doesn't.

The video does, because playback re-resolves from the page URL every time.
So once every route to the listed picture is exhausted, a frame a quarter
of the way in becomes the card's picture -- past the black lead-in, and a
fair guess at what the video looks like. It goes through our own proxy, so
the canvas can be read back, is scaled to card width and JPEG'd to a
handful of KB, and is kept: later mounts and later sessions paint it
without a request, instead of asking again for a picture that is known to
be gone.

Only for favorites, once per item, one at a time, and never for a live
stream or a manifest. Two things worth knowing, both found with the
browser rather than reasoned about: a browser fires `seeked` for its own
initial seek to zero, so taking the frame on the first one captures the
opening of every video; and the same item is on screen in more than one
place, so the captures are deduped by a promise rather than the first
asker getting the picture and the rest being told there isn't one.

e8eac70f4d Write a check into the list instead of rebuilding it 
A check asks each saved search in turn and writes back what it found, and
the list was built again from scratch on every one of those writes. So a
background check -- which has no business being visible at all beyond a
new count and a new time -- replayed the whole list's entry animation,
threw away the reader's scroll position, and took the pointer out of
whatever row it was over, several times over.

Rows are now matched by id and told what changed: the count, the name, the
line underneath, nothing else. A row is only built when it is new, gone, or
changes shape, and the entry animation belongs to a row that has arrived
rather than to every row every time. One mid-rename or mid-confirm is left
alone entirely, so a check can no longer type over the reader.

d5c859a1c7 Count only the part of a page the reader was shown 
`perPage` is a request, not a promise: a source whose own pages are 30
long answers a page of 12 with 30. The grid showed the reader the page it
asked for, the mark kept 24 of those ids, and the daily check then counted
every probe id the mark did not contain -- including ids 25 to 30 of the
same page, which were never new and no amount of looking took off the
badge. A saved search on sxyprn sat on "6" through every reload.

So the count now goes only as far down the page as the mark reaches, and
the mark holds enough ids (60) for a page larger than the one asked for.
Order does not come into it, which keeps it right for sources that shift a
listing between visits.

And the whole list can be marked read in one press, for a reader who sees
the badge and decides none of it is for them. That moves each mark on to
what the source lists now rather than zeroing the count, which would come
straight back on the next check.

6d9cc301a7 Turn the phone in one step, not through every shape 
A turn is not one shape change: the viewport passes through every shape
between the one it left and the one it lands in, and each of them
re-letterboxes the picture somewhere else. Painted, that run of hard jumps
is the stutter.

So for the length of a turn the slides are held at the size they already
had, and the moment the viewport stops moving they take the size it ended
at -- measured, not guessed. The picture moves exactly once, straight into
the position and size it then keeps. The device's own `orientationchange`
starts the hold, which is the earliest anything can know a turn is coming
and the one signal that separates it from a window being dragged wider;
failing that, the viewport swapping its long side for its short one does. A
viewport that only changes height is the browser's chrome sliding away, and
is never held.

Underneath: snapping is off while the slides are held, so the container
cannot re-anchor on the old height at the same time; a scroll arriving
during the window is put back in the event rather than a frame later, so
the stale position is never painted; and the per-frame realign only writes
what actually differs instead of costing a layout sixty times a second.

Measured over a recorded turn: the picture moves 12 times -> 2, once per
turn; the worst of those was a 660px jump between two intermediate shapes
and is now the one step into the final size; the reel is never off its step
(was 660px out); and the clip never pauses.

b9f6a78fdc Stay on the same video when the phone turns 
Rotating mid-reel jumped the reel forward a few videos. Two reasons, both
about the same arithmetic: every scroll position in the feed is index *
scroller.clientHeight, with a spacer standing in for the slides above.

A slide was 100dvh, which is not the scroller's height on a phone whose
chrome comes and goes, so that mapping addressed the wrong slide by a
growing margin; it is now the scroller's own height, which it cannot
disagree with.

And the realign window lasted two frames. A rotation is many frames and
several resizes, with the container's re-anchor on pre-rotation pixels
landing in the middle of them -- so the window now stays open until the
slide height has held still for a stretch of frames (with a clock to close
it in a tab that isn't drawing), and orientationchange and the visual
viewport open it too. Moving the feed into a picture-in-picture window
settles the same way.

tests/smoke_rotate.py replays a rotation as the browser delivers it, on a
fixture reel so nothing waits on a real source; against the old code the
reel goes from step 7 to step 12.

bc7c0047b7 Keep a whole search, and say what is new in it 
A search here is more than the words in the box: it is the source, the
channel, every filter that channel offers, and the query together. The
bookmark in the search bar keeps all of it, the one in the header opens
the list, and tapping a row puts the whole thing back.

Each saved search remembers the ids of the newest videos it showed the
last time it was opened. Once a day -- at startup, when the tab is looked
at again, and on a slow heartbeat for tabs left open -- the client asks
each one's first page again and counts how many of those videos it has
never shown. That count is the badge, on the row and summed in the
header, and it stops at 9+. Opening a saved search is viewing it, so the
count goes out and the mark moves to what is on screen now.

Nothing new leaves the device: the check is the same listing request the
grid would have made, and everything else is localStorage.

Also: handleSearch's "put this in the box without searching for it" half
is now App.videos.setSearchBox, which is what applying a saved search
needs.

tests/smoke_saved_searches.py covers it end to end against a fixture
listing whose ids the test shifts to mean "new uploads": 46 checks.

f977852253 Offer the searches from before while you type 
Searches are kept in local storage and the five that best fit what is in
the box are offered under it: the ones it starts, then the ones it starts
a word of, then the ones it appears in anywhere, most recently searched
first. Walk them with the arrows, take one with enter or a tap, dismiss
with escape. The part that matched is picked out, and rows are built from
text nodes -- these strings are the reader's own and they are going back
on screen.

The box searches as you type, so there is no submit to record and storing
every pause would fill the list with the way to a query rather than the
query: a new entry swallows the ones it grew out of ("hot", "hote",
"hotel" leaves "hotel"), and going back to something shorter adds
nothing. Enter records straight away, since that is a reader saying they
meant it.

That turned up a bug the suggestions would have run into constantly: a
search started while the box's own last search was still out was dropped
-- loadVideos saw a load running and returned -- leaving the grid on the
previous query. Changing the result set now stops the load that is
running before starting the next one.

vertical bisecting line is the same picture as the split-down button's

adb254c20b Keep the videos already playing when a panel is split 
Splitting or closing a panel changes the stride, which renumbers every
step, so the slides are rebuilt -- and the rebuild threw away the panes
along with them. Every video on screen was fetched and buffered again to
show what it was already showing.

The panes are now set aside by video id first, and whoever needs that
video next takes the pane that already has it: the same element, the
same stream, the frames it had already decoded. It all happens in one go
without yielding, so a pane is never out of the document long enough to
be paused for it. Panes the new layout has no place for are torn down as
before -- they are holding a stream open.

Pane tools are rebindable for the same reason: a reused pane comes back
under a different node in the tree, and its old buttons would otherwise
split and close the one it left.

8163693150 Load a split step's videos together, and three steps ahead 
Preloading was counted in steps and then shared out between the panels,
so with four panels only the very next step was ready and each panel did
its resolving and buffering at the moment it was swiped to -- four
panels, four starts in a row. It is now counted per panel: every panel
keeps its next three videos ready (N * 3 for a step of N), the rendered
window reaches far enough forward to hold them, and the step right
behind the one being watched buffers for real rather than taking its
metadata alone.

Their formats are resolved up front and all at once, rather than one
panel at a time as each is swiped to.

The listing is fetched several pages at a time to keep up: a page number
is claimed before its request goes out, which is what lets pages
overlap, and finished pages wait their turn so the reader still gets
them in order. A page whose request fails puts its number back rather
than leaving a hole. How far ahead to run scales with the split, since a
step of N panels gets through a page N times as fast.

1b38f9d9e7 Blur the page whenever the window isn't in front 
Losing focus -- another tab, another window, another app -- now puts the
whole page behind a blur, so an app switcher's snapshot or a glance over
the shoulder gives nothing away. It comes back on focus, on the tab
becoming visible again, and on the first touch or key, which lands on the
veil rather than on a page nobody could see.

Painted as a backdrop filter on a fixed overlay above everything the app
can show: a filter on the page itself would make every fixed element
position against the wrong box.

741786c7cf Leave the controls down while swiping through reels 
Scrolling woke the HUD, so a swipe to the next reel put the controls up
over the video arriving -- the one thing the swipe was for -- and left them
there for a second. The scroll now puts them away instead.

Removing that alone wasn't enough: the container also woke on pointerdown
and touchstart, which is how every drag begins, so the HUD still flashed at
the start of one. A press only wakes them now if it lands on a control --
which is a press on something the reader can't see while they're hidden,
and never the start of a swipe. A press that turns out to be a tap still
wakes them through the gesture layer's onSingleTap, the mouse moving still
wakes them, and dragging the scrubber keeps them up, being the one drag
that is the HUD.

Two details follow from it. The sleep sits after onScroll's suppressScroll
guard, so a resize or a picture-in-picture re-snap doesn't count as the
reader moving. And opening the feed scrolls to the starting step, whose
scroll event would put the controls straight back down, so that wake waits
a frame -- scroll events run before animation frames.

The checks live in their own file rather than in smoke_reels: one panel and
one swipe is all they need, and the split-panel suite is the heaviest thing
in the tree to run.

39a47289b9 Start the next reel as it slides in, not once it has landed 
A step began playing when the swipe was already half done -- Math.round of
the scroll position -- and only then started loading. So it slid into view
as a still picture and came to life some time after it arrived, which is
most of the waiting in a reel.

The step coming into view now starts as soon as any of it is showing, and
silently, so it doesn't talk over the one still being watched; its own
sound setting is restored when it becomes the step being watched. A swipe
carried through therefore lands on a video that is already running.

A swipe that is abandoned leaves nothing behind: the step peeked at is
stopped and put back where the peek found it -- the start for a step never
watched, where it was left for one scrolled past -- so the next swipe to it
begins at the top rather than partway through something nobody saw.

"The scroll has stopped" has to mean stopped *on* a step. Scroll events also
stop while a finger holds the list between two of them, and the first cut
rewound the incoming video under the held finger -- which is exactly the
stall this removes. A settle that finds the scroller mid-step now waits for
the snap to land.

b8a51d9ee2 Keep every panel playing on iOS, and give one of them the sound 
iOS gives a page one audible video at a time. Start a second one with
sound and the system pauses the first, so on an iPhone a split of two
showed one panel playing and one stopped -- the feed-wide unmute set every
panel audible, and the panels then took the audio session from each other
in turn.

Muted video carries no such limit, so where the rule applies exactly one
panel keeps its sound and the rest keep their picture: four pictures moving
is what the split is for, and four audio tracks at once was never the
point. The sound follows whichever panel is asked for it, and a panel the
system stopped on the way is started again.

Nothing in the platform announces the rule, and by the time the symptom
shows -- a video we started, stopped by something that isn't us -- a panel
has already died, so it is read off the device rather than discovered.
Everywhere else nothing changes: panels keep their own sound.

No iPhone here, so the rule is installed into Chromium and the real feed is
driven through it. The last check breaks it on purpose -- unmuting every
panel by hand does stop one -- so the simulation can't quietly become a
no-op. Against the code before this commit the test fails seven checks,
showing exactly what was reported: both panels unmuted, the first paused.

b4bc90372d Load a video before showing the player, not after 
Opening a video put an empty black player up at once and spun at the
viewer until the first frame arrived -- which, between resolving the
formats and the first bytes of a stream, is routinely a couple of seconds
of nothing to look at.

The session now starts off-screen: everything is built and loading, but the
card that was clicked keeps its own spinner, the page stays where it was,
and the player appears when the video has something to show. Failures
reveal it too, since the error and its retry live inside the player, and so
does a five-second timeout -- a stream that is merely slow is better
watched from inside a player that can be closed than from a card that looks
stuck.

The video is muted while it loads out of sight and restored on the way in,
because nothing should be heard from a player that isn't there. It is
hidden with opacity rather than display:none: iOS won't load a display:none
video, and the HUD's children opt back into pointer events, so they are
told not to as well -- an invisible close button must not eat a card's
click.

isActive() replaces the checks that asked "is the player open?" and meant
"is there a session": a pending one owns the same history entry, the same
card spinner and the same requests, so Escape cancels it, the back gesture
cancels it, another video takes over from it, and an update can't reload
the page out from under it.

4b03789ef2 Hand over the whole item from the info panel 
The panel is where you go to see exactly what the server said about a
video, and every time that is worth reporting somewhere it has to be
retyped from the screen. Copy JSON hands over the object instead: the
listing item, plus the extractor's payload once that has resolved.

What it copies is built where the rows are built, so the button and the
panel can't disagree about what "this video" means -- and it is the values
rather than the rendering, so a duration of 0 stays 0 instead of becoming
the panel's dash.

navigator.clipboard needs a secure context, which the app has on https and
does not on a plain-http LAN address, so the old execCommand path sits
behind it.

The test drives the real clipboard rather than the function, and the
awkward parts of a real item -- nested http_headers, a tag array, a zero,
an empty string -- are in the fixture for that reason. It and two others
also pick up smoke_grid's lean Chromium flags, without which they get
themselves killed when run alongside everything else.

051dae98cb Ask a video's own page for a thumbnail the listing lost 
sxyprn signs its CDN paths with an expiry, and the URLs the listing hands
us have generally passed theirs. They only look alive while Cloudflare
still has the bytes: add a cache-buster to one that returns 200 and it
returns 404, every time, for every one tried. The newest posts are the ones
nobody fetched while the URL was valid, so they are the ones that arrive as
holes in the grid -- which is exactly where this was reported.

Neither route can help, because both ask for the same dead address, and the
right one can't be derived: the token signs the whole path, so swapping
`full.jpg` for `small.jpg` or `vid` for `img` is just another 404. The post
page, though, always carries a freshly signed one in og:image. So when a
thumbnail has failed every way we know to ask for it, /api/poster fetches
that page and reads the picture off it -- streamed, capped, and only if what
comes back is HTML, since a page URL that turns out to redirect to the video
must cost one buffer rather than a download. Answers are cached, including
"nothing", which is the honest answer for a post that has been deleted.

Finding the page is the other half. A listing item points at the Hot Tub
server's proxy, which answers by redirecting to the video, so there is no
page there to read -- but the item also carries the Referer the media needs,
and that names the site. Its origin plus the path the proxy was going to
fetch is the page a browser would open.

Also fixes what this exposed: the retry ladder disarmed itself on its last
step, so the failure that means "the picture is gone, not the route" was
never heard by anything.

a795442634 Choose a channel by what it is, not by its name in a list 
A <select> of ninety channels tells the reader almost nothing: a wall of
bare names, nothing to say which site a name belongs to or what it
carries, and no way to look for one. The server has been sending far more
than the name all along -- a favicon, a description, tags, its own
groupings, and whether a channel still says "work in progress" -- so the
picker shows that.

It opens as a dialog in the site's own style: a search field, then the
server's groups as sections, each led by an "All <group>" row that browses
the whole group. Search matches the name, the id, the description, the
tags and the group, so "jav" finds Tokyo Motion (whose name never says it)
and "leaks" finds the OnlyFans mirrors. Arrows and Enter walk the list,
Escape closes it, and opening it with nothing typed scrolls to the channel
already being read. On a phone it fills the screen and leaves the field
unfocused -- the keyboard would cover the thing being chosen from.

Favicons load through attachThumbnail, so they get the same route race,
proxy fallback and retries as every other remote picture, with the
channel's initial behind them for the ones that never arrive.

The <select> was also where the command palette read its channel actions,
so the list lives in App.ui.channels now and the palette asks for it.

b478c51551 Keep one junk thumbnail from taking the page down with it 
sxyprn's "latest" listing sends items whose thumb is the bare string
"https:". Resolved against the page -- which is what new URL(url, location)
does with anything that isn't absolute -- that becomes our own address, so
the card raced our own HTML as if it were a picture, pinned our origin to
the proxy for the rest of the session, and asked /api/image to fetch
"https:" (a 400, every time). An address that doesn't stand on its own is
no thumbnail at all, and is now treated as one: no src, no race, no
request, and the card keeps its placeholder.

While in here: a thumbnail that failed had exactly one more chance, the
proxy, and images already on the proxy route had none at all -- so one
refused connection left a card empty for as long as it stayed mounted. A
failure now walks a short ladder instead: the other route, then both again
after a pause. Bounded and backed off, and dropped the moment the card is
rebound, so a page of genuinely dead images costs a handful of requests
rather than a storm.

191c81e55e Reach picture-in-picture the way iOS offers it 
Safari on iPhone and iPad has picture-in-picture but never implemented
requestPictureInPicture; it exposes WebKit's older presentation-mode switch
instead, and document.pictureInPictureEnabled is undefined there. Every
capability check in the player and the feed was that one property, so they
all answered "no" and the button was hidden outright on the platform where
people most want it.

The difference is confined to customPlayer: supportsPiP, pipElement, enterPiP
and exitPiP speak for both APIs, and bindPiPEvents re-fires WebKit's
webkitpresentationmodechanged -- which does not bubble -- as the standard
enter/leave events, so the feed's delegated listeners, the pane pin and the
media-key stepping work unchanged. Capability is read from the method's
presence rather than webkitSupportsPresentationMode(), which answers false
until a video track is loaded and would hide the button on preload="none"
feed videos.

There is no iPhone here, so smoke_ios_pip.py reshapes the browser to iOS's
API surface -- deleting the standard entry points and installing WebKit's --
and drives the button through it. That covers what actually broke: which API
the code reaches for.

2abdc31f56 Put the reel itself in the picture-in-picture window, so it scrolls 
A video picture-in-picture window renders one <video>'s frames and nothing
else, which is why moving through the reel from it had to be smuggled in
through media keys. Document picture-in-picture opens a real document
instead, so the feed is moved into it: #feed-view and its whole subtree are
appended to the new window's body. Nothing is copied and no <video> is
re-created, so playback continues across the move and the scroll-snap list,
the panes, the split tree and every control keep working -- they are the same
elements, in another window. Scrolling the window scrolls the reel, because
it is the reel.

The lookups in feed.js now go through the cached #feed-view root rather than
document.getElementById, since after the move the feed is no longer in this
document, and the HUD-idle class rides on that root so it travels with it.
The page underneath drops back to the grid while the feed is out, and gets it
back when the window closes.

The video window stays as the fallback: it is Chrome-only, needs a user
gesture, and a hidden tab has none -- so auto-PiP on tab switch is still the
old path. It is suppressed while a document window is open, or the browser
would tear the video out of it on the next switch.

Also fixes the picture-in-picture button, which referenced an undefined
`pane` in bindSharedControls (the parameter was named `slide`) and threw into
a swallowed promise rejection on every click.

76a078b9b5 Move through the reel from the picture-in-picture window 
A picture-in-picture window shows one video's frames and nothing else --
no markup, no scrolling. What it does have is the controls the page
declares through the Media Session API, so moving through the reel from
the window means its next and previous buttons. Those are the same
controls that appear on a lock screen, on headphones and on media keys,
and with no window open they move the feed itself.

The window rides the pane's own video. That matters for the automatic
case, and it is where the first attempt went wrong: a hidden stand-in
element was used so the window could survive the feed advancing, but a
browser only carries a video out to a window by itself if that video is
already playing, and a hidden one never is. So opening it by hand worked
-- a click is a gesture, and an explicit request needs one -- while
switching tabs could not, and the autoPictureInPicture attribute meant to
handle that case was sitting on a different element than the code used.
Both halves now point at the same video.

Stepping is what a pane's video normally cannot survive, since the feed
destroys a step's videos when it moves on. While a pane is in the window
it is pinned against teardown and its source is swapped in place: the pane
becomes the video being watched, title and poster included, and the feed
is rebuilt around wherever it ended when the window closes. Two panes can
name the same video while that is going on; the rebuild puts the steps
back in order.

The leave handler releases the pin on any leave that finds nothing left in
a window, rather than insisting the element match exactly. The two ways of
being wrong are not the same size: releasing too readily costs a rebuild
nobody sees, while a pin that never releases leaves the feed unable to
recycle that slide for the rest of the session.

Whether a window opens on a tab switch is browser policy, not ours:
Safari honours the attribute, Chrome honours it for installed apps.

451bf0f983 Pick formats by decode cost, and fix auto picture-in-picture 
Two things, both about playing several videos at once.

Capping the resolution per panel wasn't enough, because pixel count isn't
the only cost. A split panel now also prefers a progressive file over HLS
-- every HLS panel runs its own JavaScript demuxer over every segment, so
four panels means four media pipelines doing work a plain MP4 skips
entirely -- and H.264 over AV1 or VP9, which are often decoded in software
and are a cliff rather than a gradient, and 30fps over 60. The height
ceiling still comes first, so cheapness cannot argue a panel into a bigger
picture than it should have, and every format stays reachable as fallback.
The preloaded step's hls.js instances now park after buffering one
fragment and resume when the reader swipes to them, instead of fetching
and demuxing ahead for a step nobody reached.

Auto picture-in-picture had been implemented since the custom player was
written and had never worked. requestPictureInPicture() from a
visibilitychange handler carries no user activation, browsers refuse those,
and .catch(() => {}) swallowed the refusal -- so it failed silently every
time, in the reels feed and the standalone player alike. The declarative
autoPictureInPicture attribute is the form made for this: the browser is
told in advance which video should follow the reader out. The imperative
call stays as a fallback.

With panels there are several candidates and only one window, so binding
every pane made them race for it. The feed picks one deliberately -- the
panel you can hear, or the first if they are all muted -- re-picks when the
step or a mute switch changes, and releases it on close.

Whether a window actually opens is browser policy, not ours: Safari honours
the attribute, Chrome honours it for installed apps.

764e3416a3 Fit the rendition to the panel it plays in 
Four panels stutter, and the reason isn't scheduling: a quarter-screen
panel was still being handed a full-screen stream. Decoding 1080p into a
quarter of the screen costs exactly what decoding it full size costs, and
four of those at once is past what most GPUs will decode in hardware --
after which it falls back to software and the wheels come off.

So a split panel now caps by its own height in device pixels, rounded up
to the next standard rendition, and hls.js is told the same thing through
capLevelToPlayerSize since an adaptive stream picks its own. Four panels
on a 1080p screen land near 480p each: roughly a quarter of the pixels to
decode. Its buffers shrink too -- several instances each holding a minute
of video is memory and demuxing for footage nobody has reached.

The preloaded step keeps its guarantee but gets cheaper with it: those
panes use preload=metadata rather than auto, so every panel still has its
next video ready to start instantly without four more streams competing
for bandwidth with the four being watched.

The floors that make that preload guarantee hold -- one step, in both
windowBounds and preloadAhead -- now say so. Both are divided by the pane
count, and dropping either below one would leave a panel with nothing
buffered to swipe to.

Two tests. tests/unit_formats.js runs the rendition maths in node with no
browser, server or network, in under a second: picking a format is a list
in and a URL out, and it is the cheapest thing in the repo to assert.
tests/smoke_reels.py covers the panels themselves -- splitting, nesting,
controls staying inside short panes, one swipe advancing every panel,
per-panel audio surviving re-activation, and the preload guarantee.

What none of this establishes is whether four streams now play smoothly
on real hardware. Headless Chromium has no GPU decode, so it cannot say.

f0df53365d Split the reels view into panels 
A panel can be split to the right or below, and the panel that appears can
be split again, so any arrangement is reachable. The layout is a binary
tree and the leaves, read in order, are the panels of a step.

Scrolling drives all of them: with N panels a step covers N videos and one
swipe advances the whole set. That runs through every index in the feed --
opening on a video, realigning after a rotation, the prefetch buffer, the
render window -- all of which now convert between a video and the step
that holds it.

Each panel has its own sound, so two can play at once if that is what you
want. A new panel inherits the feed-wide setting rather than starting
muted, so a step built later doesn't disagree with what is already on
screen, and the feed-wide button reads as muted only while every panel is.

Two things fall out of panels that are worth knowing. The render window
narrows as panels are added -- five steps ahead of a four-panel split
would be twenty live <video> elements -- so splitting does not multiply
decoding. And splitting rebuilds around the video you are on rather than
keeping it in the panel you split from: steps are aligned to the panel
count, so it stays on screen but not necessarily first.

The per-video helpers were already written against an element holding one
video's controls, so they took a panel unchanged; a slide became the
container that fans out over them.

6e5ab68a94 Prepare cards ahead of the scroll, and insert them in batches 
DOM work cannot leave the main thread -- a worker has no document, and
nodes are not transferable -- so a card can never be compiled elsewhere.
It can be compiled *earlier*. The page already prefetches the next page's
JSON and warms its thumbnails; this does the same for the cards those
items will need, building and binding them while the browser is idle and
handing them over ready when the reader arrives.

Alongside that, three things that keep a frame from being held too long,
which is what smoothness actually reduces to when the work has nowhere
else to go:

Mounting and filling are drained against a 4ms budget rather than all at
once. Filling in one pass was a regression I introduced with the fling
deferral: it moved the stall from during the fling to the end of it.

A frame's mounts go into a DocumentFragment and enter the document in one
insertion, with filling afterwards so nothing reads layout mid-insert.

The pool is topped up with card shells during idle, so a mount during a
scroll is a rebind and not a construction: cards built mid-scroll fell
from 24 to 5 across profiling runs.

Also reverted, with its numbers kept in a comment: narrowing the overscan
during a fling. It reads like an obvious saving and measures as the
opposite -- a tight window makes cards leave and re-enter it, and mount
churn went from 88 to 155 with blocked time from 3.6s to 4.3s.

What this does not do is reduce total blocked time. Roughly three
quarters of it is browser style, layout, paint and decode for each card
shown, which no amount of scheduling removes. The deep stalls get
shorter; the thread stays busy.

e603111d70 Don't fill cards the reader is flinging past 
Profiling the reported stutter on a fixed 400-card grid: 30 cards mounted
during one fast scroll, 693ms of blocked main thread -- about 23ms per
card. Building the card is 15.6ms of that. The rest is what a mount sets
off: a thumbnail request and decode, the height correction its load
triggers, a forced layout to measure the title, and an /api/resolve call
that runs yt-dlp on the server. Measured separately, a single fast scroll
fired twelve of those, peaking at nine a second, for videos the reader
never stopped on.

None of it is work anyone asked for while the list is moving. So a mount
during a fling now only places the card: right size, right position, text
and heart in place, so the grid and the scrollbar stay exactly correct.
Everything that costs waits 140ms for the scroll to settle, and then runs
only for the cards still on screen. Whatever was scrolled past is
unmounted having cost almost nothing.

The threshold is 1600px/s, well above a deliberate scroll, so reading at
a normal pace behaves as it did. The visible trade is that flinging
through a long list shows card text over an empty thumbnail box until you
slow down.

Roughly half the blocked time was browser style, layout, paint and decode
that no amount of restructuring removes -- this avoids provoking that work
for cards nobody looks at, rather than making it cheaper.

7624ca559a Close three holes in the card release path 
A second review pass over the pool. All three are the same shape: state
or a listener outliving the video it belonged to.

attachProxyFallback replaces whatever fallback an image currently has,
so a call arriving late -- a race hitting its patience timeout after the
card was recycled -- took away the live listener and left a dead one, and
the new video's thumbnail would then fail with nothing behind it. This
one was self-inflicted: the detach came in last round to stop the
listeners accumulating, and introduced the clobber. It is token-guarded
now, like every other path that can arrive late.

The favourite pop is cleared by animationend, which never fires on a card
release() has already detached -- detached elements run no animations. So
the class rode into the pool and replayed on the next video the card
showed. Favourite something and flick-scroll to see it.

And withOrigin compared a token that dataset reports as undefined for an
unstamped card, which matched every unstamped card instead of none --
failing open in the guard whose whole purpose is noticing that the grid
has recycled the card out from under the player.

49992c1db0 Recycle grid cards instead of rebuilding them 
Scrolling the grid did nothing but destroy cards and build near-identical
ones back: a template string parsed as innerHTML, ten querySelectors, and
a listener per interactive element, every time a card entered the window.
The virtualizer now keeps a pool and rebinds a card it already has --
18us against 136us to build one, and 74-83% of mounts are served from it.

Two things had to change first. Nothing on a card may close over the
video it is showing, because the card outlives the video, so every
interaction moved to one delegated listener per event type on the grid.
And every card now has the same shape whatever it shows: the optional
parts are always present and hidden when unused, so any pooled card fits
any video. That needed a global [hidden] rule, since .live-badge and
.video-tags carry their own display.

The rest is the release path, which is where this design lives or dies.
A thumbnail carries a generation, so a race or a proxy fallback settling
after the card moved on cannot paint over the video now showing. The
player stamps the card it was opened from, so a recycled element stops
answering for it. The reveal handler, the entrance-animation listener and
the hover preview are all taken back off. Anything missed here surfaces
as one video's title, thumbnail or heart on another video's card, which
is what the smoke suite scrolls back and forth to catch.

Two incidental fixes found while measuring: bindCard no longer writes a
data-tag per tag button (dataset is a proxy, and that alone cost more
than the rest of a rebind put together -- the handler reads the label off
the button), and favorites.has no longer parses a URL for every card that
isn't a favorite by key.

b4031b5d0e Add a grid smoke suite, starting with content bleed 
The repo has no tests, and the card pool that follows is exactly the kind of
change that breaks quietly: a release path that forgets to clear something
shows one video's title, thumbnail or heart on another video's card. So the
check that matters is that every mounted card renders the video its own
data-video-id names -- asserted after scrolling down and back, which is when
cards get reused.

Passes against the current build, where nothing is recycled yet.

1dbac33359 Recognise a favorite by its URL, and take the listing's copy of it 
The same video reaches this client under two identities: saved from a
card it carries the server's id, imported from a Hot Tub backup it
carries only its URL. indexOfEntry already matched on either, but the
grid card and the player asked only whether the key was known -- so an
imported favorite left its own listing card, and the player, showing an
empty heart. All three surfaces now ask one question.

Once matched, the listing's copy is the better one: it has the id the
cards key on, and a thumbnail URL that hasn't been sitting in
localStorage since whenever the backup was taken. So a page of listing
videos rewrites the favorites it matches, keeping only the date each was
first saved -- the one fact the listing doesn't know, and the one the
sort depends on. Nothing is written when nothing differs.

Both identity sets now come from one cache dropped on write, since this
is read once per card built and per layout probe, and each read was
re-parsing the whole favorites list out of localStorage.

made minutes ago, the CDN has not generated -- while the post page itself
shows one that works (`.../img/<other token>/.../0.webp`). Nothing on the
client can guess the second from the first: each path carries its own
signature. So when a thumbnail has failed every way we know to ask for it,
the page it came from gets asked what it shows.
Cheap to be wrong about and expensive to repeat, so answers -- including
"nothing" -- are cached for a few minutes."""

// A favorite outlives its thumbnail. The picture a listing hands out is a
// signed CDN path on most sources, and the signature expires -- so a video kept
// months ago has a `thumb` that 404s, and the card that stood for it is a grey
// box with a title under it. Asking the source page for a fresh one (the
// /api/poster repair in videos.js) covers the case where the page still exists
// and still shows a picture; nothing covers the case where it doesn't.
//
// The video itself does, though: it is still playable, because playback
// re-resolves from the page URL every time. So once every route to the listed
// picture is exhausted, a frame a quarter of the way into the clip becomes the
// card's picture -- far enough in to be past a title card or a black lead-in,
// and a fair guess at what the video looks like.
//
// A frame costs a resolve and the stretch of video around that point, which is

"""A swipe counts even when the viewport just moved.
Run against a locally running backend:
backend/main.py &
.venv/bin/python tests/smoke_feed_swipe.py
Both the status and the listing are fixtures, so the reel is long enough to
swipe through and the test never waits on a real source.
A viewport change opens a realign window in which the feed holds the reader's
video in place, because the scroll-snap container re-anchors on positions
measured against the old height and must not be allowed to flip the video (see
smoke_rotate). The window used to revert *every* scroll it saw, and on a phone
that is the worst possible moment to do it: the chrome sliding out of the way
is caused by the swipe, so the window was open exactly when the reader was
swiping. The reel moved under the finger -- far enough to show the next video
coming in at the bottom -- and was then pulled back to where it started.
So the two halves have to be told apart, and the test asks for both: a scroll
with real input behind it is the reader's and is kept, a bare re-anchor is not
and is still undone.

Run against a locally running backend:
backend/main.py &

Safari on iPhone and iPad never implemented requestPictureInPicture. It has
picture-in-picture -- it just reaches it through WebKit's older
presentation-mode switch, and document.pictureInPictureEnabled is undefined,
so every capability check answered "no" and the button was hidden on the one
platform where people most want it.
There is no iPhone here, so the browser is reshaped to have iOS's API surface
instead: the standard entry points are deleted and WebKit's are installed. That
is enough to test what actually broke, because what broke was which API the
code reaches for -- not what the browser does once it is called.

"""A split step loads its videos together and ahead of time, not one by one.
Run against a locally running backend:
backend/main.py &
.venv/bin/python tests/smoke_parallel.py
The listing and the media are fixtures, so what is measured is the feed and not
somebody's CDN: every clip takes the same MEDIA_DELAY_MS to arrive, which is
far longer than a step that was preloaded needs to start.
Four panels, which is the case this is for. With one step preloaded between
them, a panel did its loading at the moment it was swiped to -- on a real CDN
that is four starts in a row, and here it is four late ones. The second swipe
is where it shows: the first lands on the step that was preloaded either way,
and it comes quickly enough that the step after it cannot have loaded since.

"""A captured thumbnail has to be a picture of something.
Run against a locally running backend:
backend/main.py &
.venv/bin/python tests/smoke_poster_black.py
Two ways a card ends up a black box rather than a picture, both of which the
capture used to keep for the life of the item -- the only test a frame had to
pass was being a few hundred bytes long:
* the frame at the mark is black. A video that opens on a fade, or whose
length nobody will say (so there is no quarter mark to seek to and the
opening frame is all there is), hands over exactly that.
* the element decoded nothing. Drawing one that has not presented a frame
gives an untouched canvas, which is a pure black JPEG about 1.6 KB long.
The fixture is black for its first three and a half seconds -- past the quarter
mark a capture aims for -- and flat orange after, so the picture on the card
says whether anything looked at what it was keeping.

A turn is not one shape change: the viewport passes through every shape

the picture somewhere else. Painted, that run of jumps is the stutter. So the

picture steps straight into the position and size it will keep, and stays

"""Splitting a panel keeps the video that is already playing, rather than
fetching it again.
Run against a locally running backend:
backend/main.py &
.venv/bin/python tests/smoke_split_reuse.py
The clip server counts what is asked of it, which is the whole point: a split
renumbers every step and rebuilds the slides, and the question is whether the
bytes already in hand survive that. The listing is a fixture for the same
reason as everywhere else -- so the answer is about the feed, not a CDN.
Each panel's <video> is tagged, so a rebuilt panel is told apart from a reused
one by the element rather than by what it is showing.

The listing and the image hosts are both served by this script rather than by a

* a `thumb` that isn't a URL at all -- sxyprn's "latest" listing sends items
whose thumb is the bare string "https:". Resolved against the page that is
*our own* address, so the card used to race our own HTML as if it were a
picture, pin our origin to the proxy for the rest of the session, and ask
/api/image to fetch "https:" (a 400, every time).
* a thumbnail whose first request fails. One blip used to mean an empty box
for as long as the card stayed mounted.
* a thumbnail that is simply gone. sxyprn's CDN paths are signed with an
expiry and the listing hands out URLs that have passed theirs, so the
newest posts arrive pointing at a 404. The item's own page still shows a
working picture, and /api/poster reads it off.

/* The direct-playability probe, tested without a browser.
*
* node tests/unit_direct_probe.js
*
* The probe decides whether the player may skip the proxy and let the browser
* fetch a CDN URL itself. Getting that wrong is not a slow video but a wrong
* one: eporner's CDN answers a browser-origin Referer with a 302 to a
* one-minute "watch this at our site instead" clip, served 206 with
* `Access-Control-Allow-Origin: *`, so "bytes arrived" was satisfied by a
* stand-in and the player switched to it mid-video. What settles it is whether
* the direct route hands back the same media the proxied one does, which is
* two stubbed fetches to check -- no server, no Chromium, no network.
