Grand is gone — remove audio_musicdevice.c, the AUDIO=grand case, the grand/grand-install Make targets, and the now-dead #ifdef AC_GRAND in main.c. AUDIO is back to {core, sdl} (A/B latency comparison). Notepat now opens a borderless window at 640×480 points / density 2 (320×240 framebuffer) so the piece can draw its own chrome on retro- resolution pixels. Cmd+drag still moves the window via the existing hit test, now applied to every non-fullscreen window instead of only the overlay variant.
