A new full-screen, touch-first edition of the player aimed at phones through
tablets - no native app, just a web page you can "Add to Home Screen".
Reuses the shared engine + look-ahead scheduler (same player loop as
player.html); new UI is a big pulsing beat display, beat-dot row with accent
grouping, huge BPM (tap to type, vertical drag to scrub), prev/play/next +/-
and tap-tempo, and a bottom sheet for set lists / patch+link loading / volume.
Mobile concerns handled:
- iOS ring/silent switch: navigator.audioSession.type="playback" + a silent
buffer warmup inside the play gesture, so audio isn't muted by the switch.
- Screen Wake Lock while running (re-acquired on visibilitychange).
- PWA: manifest.webmanifest + apple-touch meta + mobile-sw.js (network-first
app shell, passthrough for everything else) -> installable + offline.
Multi-file is fine here since it targets mobile (waives the single-file rule).
- viewport-fit=cover + safe-area insets, no user zoom, touch-action:manipulation,
overscroll-behavior:none; transport buttons flex-share the row so they never
overflow a narrow phone; responsive portrait/landscape, phone->tablet.
- Fullscreen toggle where supported (Android/desktop; iOS uses home-screen PWA).
Wired into build.sh + deploy.sh (page + PWA assets) and added to the index
gallery as PM_M-1 Mobile. New metronome app icons generated in assets/.
Conformance suite unaffected (engine untouched): 47 pass, 1 known.

Landing (index.html):
- Remove the PM_E-1 (editor.html) viewport; default the live viewport to PM_E-2.
- Repoint the vp-bar + the "design in the editor" link to pm_e-2.html. editor.html
still exists, just not featured on the landing.
PM_E-2 editor (pm_e-2.html) - the device-connection badge + Device-audio toggle:
- Group both in the header as matching .devctrl pills, side by side.
- Clear tooltips spelling out exactly what each does: the badge only REPORTS the
USB-MIDI link (green + name when a PM device is plugged in); Device audio is an
on/off switch that routes a connected device through the computer speakers and
does not require a device to toggle.
- Device-audio button now shows on/off state via colour (green when on), matching
the badge, instead of the .primary class (which clashed with the pill style).
- Fix _isDevicePort: it only matched pico/circuitpython/pimoroni/varasys, so the
native Rust devices ("PM_G-1 Grid" etc.) were never recognized -> the badge
stayed "no device" even when connected. Now matches pm_g/pm_k/pm_x/grid/polymeter.

A labelled developer/alpha section on the landing page with a brand-cyan download
button for the RP2350 Rust firmware + flash instructions, so it's grabbable from
the site (metronome.varasys.io/#rust) instead of the bare URL.

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).

A visual mockup of the Pimoroni Explorer Kit (PIM744) - yellow PCB body,
6 coloured buttons (A/B/C left, X/Y/Z right) flanking the central 320x240 LCD,
piezo + mini-breadboard at the bottom, USB-C / RP2350 silkscreen.
Canvas mirrors the firmware UI: VARASYS logo + version + run-state dot in the
header (3-channel lerp for the per-beat pulse, no more red-channel-only blend
bug); setlist tab + track name + big BPM + bar/time meters; pad grid up to
6 lanes with main-beat squares + subdivision circles + vertical gridlines.
Inputs: A = play/stop, B = tap, C = next setlist; X/Z = prev/next track with
350 ms first-repeat + 120 ms repeat; Y = -1 bpm (after 1.5 s held step = -5);
X+Z chord within 100 ms = +1 bpm (mirrors Y). Keyboard: A B C X Y Z + space.
Landing page (index.html) Explorer pane now points at /explorer.html with
h:500 (the LCD is half-height of the Kit's so the widget is more compact).
The /info-explorer.html embed handler still works for the "Specs & info" link.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds the Explorer to index.html's VERSIONS list between the Kit and Teacher
panes. file: "/info-explorer.html" since there's no explorer.html widget yet;
the existing replace("/", "/info-") logic is wrapped in an idempotent infoOf()
helper so "Specs & info" doesn't double-prefix it.
info-explorer.html also gets the standard ?embed=1 handler (matches every
other info-*.html), so the landing-page iframe preview strips chrome + auto-
sizes when the pane is selected.

A new, first-actually-buildable form factor for the 52Pi EP-0172 "Pico Breadboard
Kit Plus" (Raspberry Pi Pico; 3.5" ST7796 320x480 cap-touch via GT911, PSP
joystick on ADC0/1, WS2812 RGB on GP12, buzzer GP13, buttons GP14/15):
- pico/main.py — one self-contained MicroPython file: ST7796 direct-draw driver,
GT911 touch (16-bit register addressing), WS2812 RGB (neopixel), PWM buzzer,
ADC joystick, buttons. It parses the project's own program-string language
(verified against the web engine's semantics) and runs a non-blocking
ticks_us scheduler with an on-screen touch UI. CONFIG flags cover panel /
colour / touch / joystick calibration. pico/README.md has flashing +
calibration steps.
- kit.html — lean widget that mirrors the firmware's on-screen UI (portrait
320x480 canvas) plus a joystick / RGB / buzzer / A-B buttons; plays via the
shared engine. info-kit.html — the real EP-0172 pinout, a parts list
(~$45 incl. Pico) and the firmware to flash (downloads /pico-main.py, links
the README + source).
- Landing + embed page list the Kit; build.sh/deploy.sh build the two pages and
serve pico/main.py as /pico-main.py for download.

Previously every device .html bundled its full narrative (purpose, BOM,
dimensioned drawings, embedding docs) inside a #techinfo block that embed
mode (?embed=1) only CSS-hid — so every embedder and every landing-page
iframe downloaded all of it (showcase 77%, teacher 49% of the file) for
content no embedder ever sees.
Now:
- <device>.html is the lean widget only: header + front view/controls +
title + summary + program box. ?embed=1 still collapses to the bare
widget; the heavy narrative is gone from the payload.
- info-<device>.html (new, one per form factor) carries all the words —
purpose, dimensions, priced BOM, embedding docs — and embeds the live
widget at the top via the existing iframe + auto-resize protocol
(new shared src/infoembed.html + src/infoembed.js).
- Each device links out to its info page ("…dimensions & BOM →"); the
landing panes and viewport bar now offer both Open ↗ and Specs & info ⓘ.
- Dropped the now-dead "Show info" toggle (CSS + progbox.js).
Branding: adopt the official VARASYS "tagline on the bottom" logos from the
brand kit (light-background variant now matches; dark already did). The
tagline is baked into the PNGs, so remove the CSS .brand-tag / .dev-tag
spans and the showcase canvas-drawn tagline. Brand cyan #0AB3F7 / navy
#1C283F already match the official palette.
build.sh / deploy.sh: build + deploy the six new info-*.html pages.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Logos: the brand is now a consistent lockup — wordmark image + a crisp CSS
"Simplifying Complexity" tagline — in the shared header, device silkscreens
(teacher/stage/micro), the player (was a CSS text box) and the showcase canvas
(was drawn text; now the real logo image + tagline). Cropped the baked tagline
out of logo-light.b64 so both themes render the tagline once. Renamed device
silk logos to .dev-logo so they no longer shrink the shared header logo.
Embeds: every form factor now loads its default set lists when embedded with no
config — and the Concepts landing embeds them that way (viewport loads
<device>?embed=1 with no forced #p=; the program box reflects what the device
reports and only overrides on explicit Load).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Embed page: a form-factor dropdown that rewrites every snippet (drop-in +
plain iframe), the live demo, and the name for the chosen version; variant
table completed to all six.
- Display (Showcase): the tempo weight no longer flashes and is drawn BEHIND the
pendulum lights so it never hides a beat flash.
- Practice (Micro): a beat/sub-beat flash — the whole 14-seg display washes amber
on each step (subtle on sub-beats, brighter on the beat, full on the "1"),
latency-compensated like the other devices.
- Landing: Philosophy section moved above "Pick a form factor".
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Editor: per-lane gain knob (drag/scroll/double-click, dB, applied at schedule
time — no stutter); program box now decodes base64 set-list codes + lints
(clear ✓/✗ message). When embedded it posts its program to the parent.
Landing (Concepts) rebuilt to the spec: description first, the EDITOR open by
default in a live viewport, a summary pane per form factor (click loads it into
the viewport), and a program I/O box that shows the current program decoded (not
base64), accepts plain text OR a base64 set-list code, lints it, loads it into
the viewport, and copies it. Viewport auto-sizes + reflects the device's posted
program. Engine codec inlined for decode/lint.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Concepts is now the landing (/): index.html is the form-factor gallery with the
LIVE widget embedded in every box (editor/teacher/stage/micro/showcase/initial),
on the shared header/footer. concepts.html retired; every "Concepts" link → /.
- New shared chrome partials src/header.html, src/footer.html, src/chrome.js
(assembled by build.sh) + .site-foot / details.spec styles in base.css. Applied
to the landing + showcase this pass.
- Showcase redesign per spec: the pendulum bar IS the display — each lane's
subdivisions/accents ride along the rod as moving RGB light (all meters combined);
transparent outside the body (no black window); a printed tempo scale on the
vertical axis with a draggable weight to set tempo; start is an external button
(the real unit starts when lifted from its holder).
Next pass: roll the shared header/footer onto the remaining pages (incl. the editor
header-above-toolbar), merge Open=Info into one page per form factor with the
expandable Info & BOM, and add teacher-style dimensioned views to Stage/Micro/Showcase.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
A faded one-line monospace bar under the app shows the current patch via
currentPatch(); it brightens on hover/focus. Press Enter or blur to apply it
(applyPatch) — paste a program string and it loads; the field renormalises to
the canonical string and flashes on apply, tints red on parse failure. A focus
guard keeps refreshUI from overwriting the field while you're typing in it.
Hidden in embed mode. Refreshed from the existing updateCtx() path.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- 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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- 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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Both index.html (editor) and player.html (hardware-player mockup) now pull
their common code from src/ via a new build-time include marker
(/*@BUILD:include:src/…@*/), resolved by build.sh:
src/engine.js — audio voices (DRUMS×30), Web Audio scheduler primitives,
and the share-language codec (patch/set-list encode+decode)
src/setlists.js — SEED_SETLISTS, so the player ships the SAME default set
lists as the editor (player BUILTIN = SEED_SETLISTS)
src/base.css — reset + VARASYS brand palette + type stack
The editor inlines the CC0 acoustic samples; the player passes an empty
SAMPLES object and the shared playInstrument falls back to its synth voices,
so the device stays faithfully synth-only. Each app keeps its own state
globals, setBpm, advanceMaster/scheduler, and UI. ~400 lines of duplicated
engine code removed; the player's favicon is now the shared @BUILD:favicon@.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The source index.html now keeps small @BUILD:* markers instead of the
~250KB of base64 blobs (audio samples, logos, favicon), which move to
assets/. build.sh inlines them into a self-contained dist/index.html
(+ dist/player.html); deploy.sh runs the build first and serves dist/.
dist/ is git-ignored. Keeps the single-file deploy while stopping the
samples from eating the editing budget.
Also reframe the main page as the full web app (it is not a mockup —
only the play-only player.html device is): drop "Mockup" from the title,
the source comment, and the README intro; add Build/Files docs and
correct the "no build step" claim.

Below 580px the header becomes a column-reverse so the controls (theme,
help, logo) sit above the title, then the legend — all left-aligned.
Uses !important to beat the inline align-items/flex-wrap on the row.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Move the shortcut legend to the left, directly under the title (was
right-aligned), and break it into non-breaking segments so it wraps
only between groups (at the · separators), never mid-token.
- Header row now wraps: on narrow screens the buttons + logo sit on their
own line above the legend (controls use margin-left:auto to stay right).
- Drop the rule that hid the legend below 620px — it now shows and wraps.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Move the VARASYS logo to the right-hand control group (was left of the
title).
- Alt+↑/↓ now seeds the cue when none is set, so reordering works without
having to cue an item first (it was silently no-opping).
- Theme button uses plain glyphs (◐ system / ☀ light / ☾ dark) instead of
the 🖥 emoji, which didn't render in some browsers.

New "🎵 Song" seed list (SEED_VERSION 3): 8 bar-length segments that
auto-advance through tempo ramps (92→120 build, 132→83 outro), a 2/4
samba, a half-time shuffle, a 909 four-on-the-floor and a 16th peak —
totalling ~4:00. Also gate bar-count auto-advance on the Continue toggle
(matches its "countdown / bars" label; only bar-length items are
affected, which previously didn't exist outside this song).

Add embedded CC0 one-shots for toms (stick), tambourine, cowbell,
woodblock and claves; tomMid is the low tom pitched up (VCSL has only
two toms). Now 10 sampled voices. rim, open-hat and ride stay
synthesized (no clean VCSL source), as do beep/clap/jamblock and 808/909.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
In-app help "Source" link and README now reference

Drop the QR-code share button, its external-service warning banner/CSS,
and the api.qrserver.com handler — sharing is now copy/open link only, so
the app makes no external requests at all. README: remove QR references
and the Deploy section, refresh Features/sounds/dynamics/swing, list the
808/909 voices, and note which acoustic voices use CC0 samples.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Sample-playback engine: short one-shots are embedded as base64 WAV,
decoded to AudioBuffers at audio start; playInstrument plays the sample
when present, else falls back to synthesis. First slice covers kick,
snare, closed hat and crash from the Versilian Community Sample Library
(CC0), trimmed to mono 22.05kHz/16-bit (~117KB). More acoustic voices to
follow once the quality/size is confirmed by ear. Credit added to README.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
These machines are synthesizers in reality, so synthesis is the faithful
approach. Adds 808 (kick/snare/clap/hat/open hat/cowbell/tom) and 909
(kick/snare/clap/hat/ride/crash) voices via a shared metallic-hat helper
(6 detuned squares → bandpass+highpass) plus tuned tone/noise envelopes.
Acoustic kit will move to CC0 samples (VCSL) separately.

Pads now cycle accent → normal → ghost → mute. Ghost is a soft hit
(gain 0.25) — added as new level value 3 so set lists already saved at
the 3-level stage (0/1/2 = mute/normal/accent) keep their meaning with
no migration. Share pattern gains a "g" char; the Purdie shuffle's snare
ghosts now use it. Ghost pads render faint with a · marker.
Help: explain that set lists/items/log live only in localStorage and how
to move or share them (Share set-list link / Share settings link /
Export-Import).

Two seed set lists instead of one mixed "Demos":
- 🥁 Styles — grooves/feels: four-on-the-floor, swing ride, Purdie
half-time shuffle (triplet grid, backbeat on 3, snare ghosts), Samba
(2/4, surdo on 2), Nañigo (6/8 bembé bell), 6/8, 7/8, 5/4.
- 🎯 Practice — polyrhythms, triplet hats, accent demo, tempo builder,
gap trainer.
Seed is now versioned + additive: a bumped SEED_VERSION adds any seed
list whose title isn't already present, without clobbering or re-adding
the user's lists.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Pads are now 3-state instead of on/off: click cycles accent → normal →
mute. Default keeps the first step of each beat accented (the rest
normal), so existing grooves are unchanged in feel; legacy on/off masks
migrate (on-downbeats → accent, on-subs → normal).
- Audio gain is driven per step by level (accent 1.0 / normal 0.6);
the old auto group-start accent is replaced by explicit per-step level.
- Swing: "swing 8th / swing 16th" subdivision options apply a triplet
(2:1) long–short feel to even subdivisions (per-lane).
- Share language: pattern uses X (accent) / x (normal) / . (mute), and
the sub token takes a trailing s for swing (e.g. ride:4/2s). The
default-accent pattern is omitted; legacy x/. still parse.
- Demos: "Swing ride" and an accents example.

Cue/commit model for moving through a set without audible gaps:
- Arrows/Home/End/PgUp/PgDn move an amber cue cursor across set lists.
Enter commits with a SMOOTH cutover at the next bar; Shift+Enter a
RUDE cutover at the next beat. N/P are rude quick-steps; Esc cancels.
- One gap-free cutover (armSwitch → scheduler horizon-cap →
performCutover) replaces the old stop()/start() switch — the audio
clock stays continuous across every transition (manual or auto).
- Per-item bar length (b<n> patch token + Bars input) with a bar
countdown; Continue auto-advances at the boundary (cross-list aware).
Each segment owns its tempo/ramp and resets at the cut.
- Decouple loaded vs viewed list (loadedSL) so the playing item can
live in a list you're not currently viewing.
Set-list panel: editable name combobox (rename in place; the ▾ menu
lists the set lists with "+ New" last), auto-growing description,
add-item row moved below the list, trimmed hint.
Add an inline SVG favicon (brand-cyan metronome on navy).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Move the VARASYS logo to the left of the title and switch to the
tagline-bottom lockup, with theme-aware dark/light variants swapped
via CSS (both inlined as data URIs).
- Right-justify the theme/help buttons; drop the shortcut legend to its
own line so the buttons no longer wrap on medium widths.
- Save button: wrap it so the tooltip shows while disabled, and make the
tooltip dynamic (why it's disabled vs. which item it overwrites).

Inline the compact cyan VARASYS banner (base64 data URI) in the header,
between the shortcut legend and the theme/help buttons, linked to
varasys.io. Inlined rather than shipped as a file so deploy.sh's
single-file publish still covers it; the self-contained banner reads the
same on light and dark themes.

LICENSE holds the verbatim AGPL-3.0 text. index.html carries the SPDX
header + notice; README gains a License section noting §13 is met by the
in-app source link (git.varasys.io/VARASYS/metronome).

The real conflict wasn't the key: shortcuts bailed whenever ANY form
control (slider/checkbox/menu/button) had focus, and those keep focus
after use — so P/T/A/N seemed dead most of the time.
- Guard now stands down only for text-entry fields (text/number/textarea/
contenteditable), so shortcuts work right after you touch a slider or
checkbox.
- Space always = play/stop (preventDefault so it won't scroll, toggle a
focused checkbox, or re-fire a focused button) — the DAW standard,
which also fixes the original Space/checkbox conflict.
- Arrow keys still defer to a focused range slider / select.
- Legend, help overlay, README updated back to Space.

- Pad row now shows beatsPerBar × subdivision pads, each individually
toggleable (the subdivision control sets pad resolution). Subdivision
pads render smaller; downbeats labeled; group/beat gaps preserved.
- Mask (beatsOn) is now per-step; playhead tracks the current step.
recomputeLane remaps on grouping/subdivision change and migrates legacy
per-beat masks (saved data, short share patterns) by expanding across subs.
- Share language: =pattern is now per-step (len = beats × sub); short
per-beat patterns still accepted and expanded. README updated.
- Removed the Sig time-signature preset dropdown (confusing vs subdivision).
- Help dialog: link to git.varasys.io/VARASYS/metronome + note that it's a
single-page app you can save & run offline, but file:// won't auto-save
the set list (export a backup).

- Move per-item 💾 out of set-list rows into one 💾 Save next to Tap; it
overwrites the loaded item and is disabled when no item is loaded.
- History list: red ✕ on hover deletes one session; Clear all wipes
history for the current item only.
- Bump dark-display text again (BPM 80px, timers 26px, status 19px);
widen the display column to fit.
- README: play key Space -> P.

- Each meter lane has an 'enable' checkbox right after its number (default on,
green-dim row when off); replaces the right-side 'mute'. Renamed mute→enabled
throughout (scheduler, snapshot, share '!' flag, 1–9 keys, now-playing). Old
saved data still loads (back-compat).
- Features area redesigned into highlighting boxes (Gap trainer / Tempo ramp /
Timers); trainer & ramp boxes light up + un-dim when enabled.
- Set list 'Continue' mode: per-item countdown (saved in each item, 'cd' token),
and when a playing item's countdown hits 0 it auto-loads the next — so a list
with countdowns plays straight through.
- Removed the in-app QR (vendored qrcode.js); 'QR ↗' now opens api.qrserver.com
with the link, behind a banner warning it's a third party (verify it decodes).
