New in 0.4 — mark the trouble spots inside your loop:

• Practice marks — Shift-click the zoomed timeline to drop marks inside your loop. Click a mark and the loop plays from that point to the end; click it off to run the whole passage again.
• Saved loops now capture your practice marks too, so a marked-up passage comes back next visit.
• Cleaner zoom strip — the loop fill now runs flush to the cursors, and the background hatch is gone.

New in 0.3 — shape how a passage sounds, not just where it loops:

• Change the key without changing the tempo — transpose up or down by up to 12 semitones, and hold Shift to fine-tune in cents.
• Count-in — a metronome counts you in before the loop starts, so you come in on time. Set the tempo, time signature, and how many bars.
• Saved loops now capture your zoom and count-in too, and you can rename a saved loop or replace it with your current one.

Loop now sticks where you left it
- Loop on/off persists across reloads + video navigation
- Dropped stale-loop jump: switching videos no longer yanks playhead to leftover loop position
- Loop UI scoped to /watch pages only

Panel mounts reliably
- Retries mount until video + timeline exist — fixes panel sometimes not appearing on slow/SPA loads

New
- Cross-device sync of saved loops — loops now sync across devices via storage.sync, with a one-time migration of existing loops and per-video keys (local fallback when sync unavailable).
- Move the loop as a fixed-length window — Shift+drag a handle (main timeline) or a zoom cursor to slide the loop while keeping its length; [ / ] step and nudge the window; playback seeks to the new start on move.

Fixed
- Loop band misaligned on chaptered videos — band, handles, and click-to-set now track the native playhead across chapter gaps (was drifting ~9px right). Headline fix this release.
- Zoom drag could stick — playhead/cursor drags now release when pointer capture is lost off-element.
