+### [2026-07-25 22:05] Task: Fix piano roll selection, playback, marquee drag/resize/move
+- **Tóm tắt thay đổi:** (1) Fix playback duration — min 16 beats when no notes exist. (2) Selection marquee: green transparent (#22c55e), full-height from top to CC lane. (3) Document-level mousemove/mouseup for marquee drag (không dừng khi ra khỏi grid). (4) Edge resize handles (left/right) cho marquee. (5) Body drag (move) cho marquee. Hiển thị marquee trên cả grid canvas và CC canvas.
