1. Press play on any title below. It streams a real video so position tracking is real, not simulated.
2. Pause, switch tabs, close the tab, or hit "Close & Save" — each of those saves your exact position to Continue Watching (locally, and via watchNextUpsert on the native bridge if present).
3. Click that title's card in the Continue Watching row and it resumes from the exact second you left off. Finishing a video removes it automatically via watchNextRemove.
4. The playbackUri sent to the native side is this page's own URL with ?play=<id>. If the OS Watch Next tile is opened with that URL, this page auto-resumes the same title on load — so the same logic covers both "click the card in this test page" and "click the real Android TV Watch Next tile".
