feat(web-ui): add an EPG timeline band to the web player (#771)
Implements the EPG timeline requested in #770.
**What it adds** — a pannable programme ruler above the existing
progress bar:
- tiered ticks (hour / half / quarter) labelled with the whole hours
*and* every programme boundary, deduplicated, collision-avoided and
pinned inside the ruler
- blocks with past / live / future states, plus a catch-up marker for
replays the source can serve
- a draggable playhead with a live time + programme-name bubble; release
to seek, never into the future
- hover details (name + start/end) with a dwell delay so crossing blocks
does not flicker
- click a finished programme to replay it (confirmation first), the live
one to return to the live edge, a future one to be told it has not aired
- an always-visible day label in front of the pan buttons (today 9/17 -
tomorrow 9/18 style)
- a marquee for names wider than their block
**Design notes / deviations from the issue**
- *Window instead of a virtual list*: a bounded window (±90 min around
playback, snapped to the tick grid) pans by buttons, wheel or drag. One
channel 48 h is only ~50-100 blocks, so nothing needs virtualising; the
fine grid is a CSS gradient and only the programmes intersecting the
window are in the DOM.
- *Palette*: the blue gradient family of the progress fill, and the live
badge rose for the now line, instead of the issue red/orange/grey, so it
stays consistent with the existing player and the simple theme.
- *Tooltip content*: name + start/end only. desc/category would mean
widening the XMLTV parser and EPGProgram; left out to keep this PR
front-end only.
- *Replay confirmation*: the M3U carries no catchup-days, so the client
cannot know the upstream catch-up window; clicking a finished programme
asks before trying.
- *Measured placement*: label positions, collision decisions and marquee
shifts are measured from the DOM and replayed through a ResizeObserver
(sidebar toggle, fullscreen, PiP, rotation) and document.fonts.ready,
because none of those re-render the band.
**Verification**
- `pnpm web-ui:test` — 98 tests pass, including 44 new ones for the
timeline geometry / axis labels / tap decision table and 6 render-level
checks
- `pnpm type-check:tsc`, `biome check`, `vite build` clean
- interaction paths and ruler geometry measured in a real (headless)
browser, before and after a width change
No docs change: `docs/guide/web-player.md` already covers EPG +
time-shift. Happy to add a section if wanted.1 parent 96ba191 commit f42d89f
