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.

Reworks the mobile player's controls per use on a phone:
- Set list + track are now two dropdowns at the top (with the volume slider +
theme/fullscreen beside them); drops the hamburger/bottom-sheet menu. The
track dropdown stays in sync with prev/next and set-list auto-advance.
- Tempo grid adds coarse -10/+10 buttons above the fine -/+ buttons, laid out
as a 4-col grid with prev/next and play/practice in the centre columns.
- Separate Play and Practice transports: Play runs the metronome without
touching the practice log; Practice runs AND records a session
(metronome.logs, same format/key as the editor: {at,name,durationSec,bpm,
lanes}, per-track history, sub-3s blips skipped).
- Tap Tempo restyled as a real button.
- Collapsible practice log: a thin bar at the bottom opens a bottom-sheet
showing past sessions for the current track (date - duration @ bpm), with
per-entry delete and clear-this-track.
Landscape phones switch to a two-column layout (pulse left, transport right) so
everything fits without vertical overflow. Engine untouched.

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.
