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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QBDkEXP4htyXTCZUwMLphd
