/* M III D O — Beat Pad workstation, v2 (2026-10-07).
   One screen, no scrolling between parts: transport on top, the sound browser
   as a side panel, and every sound on one shared timeline. One-shots are note
   lines (length and strength), loops are clips. A single playhead crosses all
   of it. Phones get their own layout with the browser as a bottom sheet. */
