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).

Power: standardise the whole family on a single USB-C input — drop the Micro's
2×AA and the Stage's 9V DC pedal jack (+ buck/reverse-polarity). Bring a power
bank; nothing internal to wear out. BOMs updated (Micro ≈$35, Stage ≈$56) and
all copy/cards/READMEs follow.
Micro form: detach the two end caps from the body with a gap (set-back, darker
end faces) so the TRS/USB-C jacks read as being on the ENDS of the bar, not the
front panel.
Landing: add a Philosophy section — "program on the web, play on any device"
(author once → load the program string into whichever form factor fits) and
"USB-C power everywhere — no batteries" (future-proofing rationale).

Reworks the Micro per the new brief: a long, narrow extruded-aluminium bar you
patch into your signal instead of a little box.
- Better display: amber 4-char 14-segment (Adafruit font) that shows BPM *and*
short track names, replacing the 3-digit 7-segment. Off-segments kept very dim
so the lit digits read clearly.
- Roller instead of knob: a recessed, clickable horizontal thumb-roller —
roll = tempo, press = start/stop, hold + roll = switch track.
- New form/I-O: 1/4" TRS in on one end; USB-C + 1/4" TRS out on the other;
USB-C or 2×AA power (battery gauge on the face). Click is summed into the
signal in the analog domain (+ a small monitor speaker).
info-micro, concepts and the landing card updated to match; BOM reworked
(analog path + 2 jacks + 2×AA + 14-seg) → ≈ $38.

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).

Each form factor now has an information page (purpose + live embedded widget),
with priced BOMs only on the buildable hardware (Stage ≈$59, Micro ≈$28):
- info-editor.html / info-initial.html — purpose only (web app / concept)
- info-stage.html — purpose + the priced BOM moved out of stage.html
- info-micro.html — purpose + a new ~$28 practice-unit BOM
stage.html drops the BOM panel (+ its .bom CSS) and gains a "Spec & BOM" link;
the shared .bom/.sub table CSS lives in src/base.css. "Info" added to every
page nav and to the concept cards. Wired into build.sh + deploy.sh.

- 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.

- Shared site header in src/base.css (.site-head/.site-nav/.brand-logo + theme-
aware logo + .tbtn). Applied to player/stage/micro (replacing their text
topbars) so the VARASYS logo + tagline + Editor/Concepts nav is on every page.
- Rebrand the editor: "Stackable Metronome" → "PE-1 — PolyMeter Editor" (title +
h1), with a Concepts link in its header.
- New concepts.html — the PolyMeter Concepts library: cards for the editor and
each form factor (PM-1 Initial/Stage, PM-µ Micro) + a "more coming" card.
- build.sh + deploy.sh build/deploy concepts.html; deploy.sh now loops over pages.
