Me Here 400d896518 Add PM_G-1 "Grid" form factor (Pimoroni Pico Scroll Pack) + Rust core/driver plan
New form factor: a plain RP2040 Pico + Pico Scroll Pack (PIM545) -- a 17x7
single-colour LED matrix + 4 buttons. The 7x17 matrix maps onto the editor's
lane x step pad grid.

- pico-scroll/: CircuitPython firmware (DEVICE_ID "G"). Engine/scheduler/SysEx/
  live-sync copied verbatim from pico-explorer (engine byte-identical, so it stays
  on the track-format conformance lineage); vendored bulk-framebuffer IS31FL3731
  driver (pins/map verified from pimoroni-pico); three LED views (Grid/Pendulum/BPM);
  4-button input. Audio over USB-MIDI (no onboard speaker); optional P_BUZZER.
- grid.html + info-grid.html: widget page (canvas mirrors the 3 LED views) + spec
  page with a ~$29 BOM.
- Registered in build.sh (precompile + ASCII assert + pm_g1_circuitpy.zip), deploy.sh,
  embed.js, embed.html, index.html gallery, and both editors' FW_PATHS (device id G).
- docs/rust-port.md: core/driver architecture (pm-core no_std engine+protocol; per-board
  drivers behind embedded-hal/embedded-graphics traits). CLAUDE.md + livesync-protocol.md
  note the new edition + device id.

Python firmware stays in parallel with Rust (no abandonment yet).

/* VARASYS PolyMeter — embed loader (zero-dependency, ~1 KB).
*
* Drop a placeholder + this script into any page:
* <div data-varasys-metronome="micro" data-patch="v1;t120;kick:4;snare:4=.X.X"></div>
* <script src="https://metronome.varasys.io/embed.js"></script>
*
* Attributes:
* data-varasys-metronome editor | kit | initial | teacher | stage | micro | showcase (which form factor)
* data-patch a PolyMeter program/settings string (preloads it)
* data-setlist a base64url set-list code (alternative to data-patch)
* data-width / data-height iframe size (default 100% × 300; height auto-grows)
*
* Each placeholder becomes an <iframe src=".../<page>?embed=1#p=<patch>"> (the page's
* own ?embed=1 mode strips the site chrome) and auto-resizes to the widget's content.
