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).

README was stale (pre-dating several shipped changes). Rewrite it to match reality:
- voices are all synthesized now (KIT_ALIAS -> 808/909); drop the VCSL samples
narrative, the @BUILD:samples wording, and the sample credits.
- document the lean-widget + separate info-<device>.html page model (was 'Open=Info').
- add kit.html + all info-*.html to the Pages table; add the new src/ partials
(header/footer/chrome/progbox/infoembed), pico/ firmware, and pico-main.py to Files/Build.
- document the share-grammar additions: GM note numbers, Euclidean (k,n[,rot]), per-lane @<db> gain.
- add a 'Build it (hardware)' section for the PM_K-1 Kit + MicroPython firmware.
embed.js: add the 'kit' form factor to the variant map (it previously fell back to micro),
so data-varasys-metronome="kit" embeds kit.html as the README now documents.

Sync: the visual playhead now advances on a latency-compensated clock
(currentTime − outputLatency||baseLatency) so the on-screen pulse lands when the
click is HEARD, not when it's queued — previously the visual could lead the audio
by the output buffer / Bluetooth latency (up to ~a subdivision). Applied to
editor, player, teacher, and the new pages; also bound the visual queue (vq trim).
No data races: single-threaded; only the rAF draw touches vqPtr/currentStep, and
each vq entry carries the exact scheduled time of its sound.
stage.html — foot-pedal stompbox: two heavy footswitches (Tap=tempo / hold=start-
stop, Next=item / hold=prev), 1/4" expression-pedal input → tempo sweep, big
floor-readable RGB beat light + angled TFT, analog instrument pass-through.
showcase.html — pyramid display piece: an RGB-light pendulum easing to each beat
plus per-lane segment rows showing subdivisions/accents/mutes (canvas).
Both: dual USB-C (data+power and power-thru) to daisy-chain off one source.
Wired into embed.js (stage, showcase variants), build.sh, deploy.sh, the
concepts gallery + landing cards, info-stage.html (~$52) + info-showcase.html
(~$39) with BOMs, and the README.

The full-feature desktop console (big TFT, arcade buttons, instrument pass-through)
is repositioned as the "Teacher" for studio desks and lessons:
- stage.html -> teacher.html, info-stage.html -> info-teacher.html (git mv)
- all links/paths, the embed variant (stage -> teacher), nav, cards, embed docs,
README, build.sh + deploy.sh updated; deploy cleans the stale live stage files
The "Stage" name is now free for a forthcoming foot-pedal stompbox (/stage.html).

The site now opens on a proper front door: a hero (logo + tagline + pitch),
an "Open the Editor →" CTA, and form-factor cards (Editor, Stage, Micro, Embed)
linking out to each page + info. The PE-1 editor app moves from index.html to
editor.html; every "Editor"/"Open" link, the embed.js editor variant, and the
editor's own brand-logo (now → /) are repointed. build.sh + deploy.sh build and
publish both index.html (landing) and editor.html (app).

- Every form factor supports ?embed=1: a head flag (set on <html>, no flash)
strips the site chrome (base.css [data-embed]) + page-specific panels, leaving
just the widget, and posts its height so the host can auto-size it.
- Config/settings string preloads via the existing #p=/#sl= hash. Added that
hash handling to micro.html (it previously only loaded built-in tracks).
- New embed.js loader: <div data-varasys-metronome="micro" data-patch="…"> + one
<script> → an auto-sizing iframe to <page>?embed=1#p=…. New embed.html documents
it and dogfoods a live embedded widget.
- "Embed" nav link added across pages; build.sh/deploy.sh build embed.html and
serve embed.js.
