Seedbox v0.1 + firmware, generic kit/synth, ROOT/SCALE pages
First commit of the repo. Contents beyond the v0.1 simulator and layout:

- Full Pico 2 W firmware (firmware/app, drivers, engine port, host test).
- BANK page and 404 mode A/B removed; learned pads play exactly what was learned.
- 404/MiniFreak renamed to KIT/SYNTH throughout (jacks, code, sim, docs,
  layout labels; wiring rebuilt).
- ROLL returns to page select after a re-roll; a freshly learned track turns on.
- LCD contrast 66.
- ROOT and SCALE pages: 21 scales, AUTO = the seed picks; global and sticky.

Intended music change: the scale table grew from 8 to 21 and AUTO picks from
all of them, so every seed's scale changed. Vectors regenerated with
npm run vectors, plus new key-override cases. Flash record is now version 2.

# Panel
Landscape layout for a plastic enclosure of about 80 × 150 × 40 mm. The interactive tool (`tools/panel.html`) takes your box size and hole diameters and redraws this, with a fit check.
![Panel layout, landscape](svg/panel-landscape.svg)
- **Left zone**: the screen (on top of the lid), with the encoder and RUN under it.
- **Middle zone**: ENERGY, DRIFT and SEED.
- **Right zone**: the 4 × 3 block, in the same order as the screen map: 11 track buttons, with the RUN toggle in the top-right corner. Check at test fit that the toggle's body clears the OUT SYNTH jack behind it on the back wall.
- **Back wall**: the USB slot for the Pico, and three 3.5 mm MIDI jacks (IN, OUT KIT, OUT SYNTH).
## Inside the box
- **Stripboard**: it lies on the floor with its top edge (strip A) against the back wall.
- **USB**: the Pico's micro-USB socket ends up about 41 mm from the board's left edge and about 16 mm above the *inside* floor. That stack is foam tape ~1, board 1.6, female header 8.5, the Pico's header spacer 2.5, Pico 1, half the socket ~1.4. Measure your own before cutting the slot.
- **Slot size**: cut it big enough for the plug's moulding (about 12 × 8 mm), not just the metal tip. The plug has to reach the socket through the wall's thickness.
- **Fit**: the board is 71 mm front to back, which fits the box's inside depth with a little to spare. Pot and button bodies hang down from the lid above it.
- **Under SEED**: R4 (lying flat) and pads P3/P4 sit right under SEED. Keep those two wires low and check how deep your SEED button reaches before closing the box.
## Drill list
Coordinates are from the lid's top-left corner, in mm, for the default sizes in the tool. Wall holes use x as drawn, which matches the lid view; heights are from the inside floor. Re-run the tool with your measured parts before drilling.
