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.

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.

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).

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).

- 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.

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).

- 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.
