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.

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).

- 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).

- Drop the false "vendored QR library" line; state it's a single
self-contained, zero-dependency file and document offline use.
- Fix keyboard shortcuts to match the in-app help: remove the
non-existent R toggle, add Alt+↑/↓ (reorder), 1–9 toggles a lane.
- "GM drum voice" → synthesized; set-list items load on click (no ▶
auto-start); QR is an external service; clarify release.sh.

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).

- Removed the set-list show/hide toggle and the R shortcut / Esc-close / close ✕.
The panel is always visible: sticky side column on desktop, stacked below the
metronome on mobile. Theme/help buttons stay right-justified.
- Added practice timers in the gap/ramp area: an Elapsed (count-up) timer and an
adjustable Countdown (minutes; 0 = off), each with a reset. Both advance only
while the metronome runs; countdown reaching 0 stops it (turns amber under 10s).
- '+ Add meter' button is now just '+'.

- Set-list rows are now click-to-load (the transport is the only play/stop); the
per-item ▶/⏹ and ↑/↓ buttons are gone. Reorder via Alt+↑/↓ (tooltip + help).
Selected row is highlighted and reveals compact 💾 (save-back) / ✕ (remove).
- Replaced the main-screen preset dropdown with a 'Now loaded' info block showing
the item name, config summary, and the set list's title + description.
- Presets consolidated into set-list items (removed preset functions/UI). N loads
the next item; shortcuts help + demo description updated.

- Share menu now opens a dialog with a copyable link AND a QR code (scan to open
on a phone); generated locally by vendored qrcode-generator (MIT). deploy.sh
publishes qrcode.js alongside index.html.
- README documents the share language grammar, sounds, URL forms, shortcuts,
versioning and deploy.

- Compact human-readable patch language encodes tempo, lanes (sound/grouping/
subdivision/pattern/poly/mute) and practice settings (trainer, ramp).
- Share menu (⋯) copies links: settings as #p=<patch> (readable) and a whole
set list as #sl=<base64url>. Opening such a link applies/imports it on load.
- Seeds a '✨ Demos' set list (once) with 10 examples authored in the language:
grooves, 5:4 / 3:2 / 3-lane polyrhythms, 7/8 6/8 5/4, triplets, ramp, trainer.

- App is now a flex shell (#app): the set-list panel docks as a sticky side
column that pushes the metronome instead of floating over it.
- Collapses via the header 'Set Lists' toggle; falls back to an overlay drawer
below 820px. Defaults open on desktop, closed on mobile.

- VERSION holds the formal version (0.0.1), single source of truth.
- deploy.sh stamps the served HTML: "X.Y.Z" on a clean commit tagged v<VERSION>,
else "X.Y.Z-dev.<utc-ts>.<sha>[.dirty]".
- index.html shows the build version in the header badge (APP_VERSION).
- release.sh cuts a formal release (sets VERSION + tags v<VERSION>).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Tempo ramp gains a start BPM and signed (up/down) steps.
- Presets and set-list items now capture practice settings (trainer + ramp).
- Set-list items: per-item ▶/⏹ play, 💾 save-back, per-item history view.
- Log & backup moved into a ⋯ menu; "+ Add meter" moved below the lanes.
- Light/dark theming (OS-aware + toggle, persisted) and mobile/desktop responsive layout.
- Keyboard shortcuts (Space/T/↑↓/A/R/N/1-9/?) + help overlay; fixed dead Tap button.

index.html: single-file browser mockup of the polymetric groove trainer —
stackable meter lanes, subdivisions, odd-meter grouping, per-beat patterns,
GM percussion voices, true ratio polyrhythm (poly toggle), presets, set
lists with a recordable practice log, and keyboard shortcuts.
deploy.sh: copies index.html into the Caddy web root that serves
https://metronome.varasys.io (no restart needed).
