Device screen redesign (CircuitPython app.py), built proportional to WIDTH/HEIGHT
so it scales to other panels (one adaptive firmware, per-panel config — not a fork):
- gen_assets.py bakes logo.bin (VARASYS wordmark, no tagline), midi.bin (DIN-5),
usb.bin (trident) as 4-bit-alpha bitmaps (same packing as the fonts).
- Header: VARASYS logo (brand cyan) replaces the "PM_K-1 KIT" text; MIDI icon goes
green when a host is listening, USB icon lights when supervisor.runtime.usb_connected.
load_alpha/make_glyph are non-fatal — a missing .bin falls back to text, never a
black screen (addresses the corrupt-file failure mode we just hit).
- Pad grid: filled squares on main beats, hollow outline squares (outer+inner rect) on
off-beats; playhead fills the lit pad. Vertical gridlines at the master lane's beats
(full height) so beats line up across lanes.
- Stopwatch (m:ss) + bar counter (master-lane cycles), refreshed ~4x/s only on change.
The .bin assets ship in the drive bundle (the A/B updater only pushes app.py), so a
one-time re-copy is needed to pick them up. APP_VERSION -> 0.0.2.
