From on-board feedback (works well; minor tweaks):
- Pad grid uses circles now: big circle on each beat (division), small on the
subdivisions (vectorio.Circle — native, no extra cost), coloured/lit as before.
- Lane labels use a new small font (font_s.bin, ~12px via gen_font.py) so they're
half-size and show more of the voice name (e.g. 'hatClos').
- LED was blinding -> LED_BRIGHTNESS scale (default 0.15) applied on every write.
- Residual tearing -> SPI back to 62.5 MHz (vendor speed; smaller tear window on a
panel with no tearing-effect pin). Both are CONFIG flags.
Verified by rendering the full scene headless. font_s.bin added to gen_font.py + bundle.

Four firmware improvements (web simulator already had these):
- Smooth lettering: replace the upscaled 8x8 bitmap font (and the 7-seg BPM) with
baked anti-aliased proportional fonts (DejaVuSans-Bold 22 + 78), rendered by
blending fg over bg through a 16-entry alpha LUT. Generator: pico/gen_font.py.
- All grooves: PROGRAMS now carries the full web set list (23 grooves), not 5.
- Fix: the RGB LED stayed lit when stopped — the stop path now zeroes the colour
and the fade only runs while playing (led_off()).
- Fix: the on-screen play button played one beep then stopped — a finger held past
the old lockout re-fired the toggle. Touch is now edge-detected like the hardware
buttons (fires once on finger-down, ignores held).
