- Sheet top now pins to the player's exact bottom edge (JS measures #ytpWrap height into --hl-sheet-top; 56.25vw fallback), so no title/actions row shows between the video and the sheet. Recomputes on open and on resize/rotate. - Coach-note overlay on mobile is now a slim 2-line caption pinned to the very bottom of the player instead of a 16px block mid-frame, so it no longer covers the video. Full note stays readable in the sheet. Co-Authored-By: Claude Opus 4.8 <[email protected]>
