setlists.js (shared by all pages):
- Removed the "Song (continuous)" and "Notation showcase" seed lists.
- "Styles" is now a rich, genre-true collection (16): rock, pop 16ths, funk,
disco, Motown, blues shuffle, jazz swing, bossa, samba, reggae one-drop,
afrobeat, hip-hop, metal, 6/8 ballad, 7/8, 5/4 — full grooves to jam over.
- "Practice" is 15 drummer drills to learn those styles: hat subdivisions,
ghost-note backbeats, 16th hand control, shuffle/jazz ride, bossa & 3-over-4
independence, dynamics, double bass, hemiola/5-over-4, tempo & gap trainers.
- Dropped the cartoon emoji from the titles. All patches validated: every lane
parses and pattern lengths match their meters.
Mobile icons — less cartoonish, subtly musical:
- Volume rail now reads p … f (piano/forte dynamics) instead of speaker emoji.
- Save 💾 -> ↧; library +/✕ instead of ➕/🗑.
- Practice-sessions empty state uses a treble clef instead of 🎼.
Engine untouched; conformance passes.

- Top section aggregates the CURRENT track across all sessions (track picker
defaults to the metronome's current track, persisted via metronome.curtrack):
total time / plays / bpm range, plus a per-session comparison table so you can
watch a single track progress across days.
- Each session is now a collapsible <details>: the summary shows a friendly
timestamp ("Fri Jun 16 at 2:46 PM") with total/practiced/track-count; the note
+ per-track aggregate table + delete live in the expanded body.

Bigger rework of the mobile player around a new "practice session" concept,
plus a second page to review sessions.
Transport / sessions:
- Practice now starts a continuous SESSION clock and begins practicing the
current track. While practicing, the Play button becomes Stop and Practice
becomes Pause, so Practice starts/stops individual tracks while the session
clock keeps running. Stop (the Play button) ends the session and records it.
- Plain Play still runs the metronome with no session/recording.
- Each track-practice is one segment {name, at, sec, bpm}; sub-3s blips are
skipped. A session = {at, endedAt, clockSec, note, segments[]} stored under
metronome.sessions (replaces the old per-track metronome.logs sheet).
- Switching track / set list mid-session rolls the current segment over.
Display:
- Removed the Tap Tempo button; the BPM display now does it: tap = tap tempo,
hold = type an exact value, vertical drag = scrub.
- Detail panel shows every lane (canonical share-token chips, disabled lanes
struck through) and the active features: bar count, end behavior, ramp, and
gaps (trainer play/mute).
- Meter line shows live bar count with total (e.g. "bar 4 / 16") and elapsed
play time; the bottom bar shows live session time + track count while
recording, and links to the sessions page otherwise.
New page mobile-sessions.html: lists saved sessions, each with an editable note
(autosaved) and an aggregate table of tracks practiced in that session
(track - time - plays - bpm range), with per-session delete. PWA scope widened
to /mobile so both pages stay in the installed app + offline (SW v2).
Engine untouched; conformance suite unaffected.
