Replace the vertical EPG list/panel with a single horizontal timeline ribbon
(`app-epg-timeline`) shared across all live surfaces — the M3U player, the
unified live tab, and the Xtream and Stalker layouts. It preloads a multi-day
window and supports scroll, zoom, day navigation, short-programme tiers and
per-state empty/error views; the programme-details dialog is restyled to match
and now shows the channel logo.
Timeline / UI
- Auto-focus the currently-airing programme on channel select — instant
(`behavior: 'auto'`), centred, and deduped by programme-set identity so the
30s tick / zoom / re-emits never cause flaky re-jumps.
- Wide-tier cards show a dimmed description preview under the title; title and
preview clip on whole lines (`flex-shrink: 0` + `-webkit-line-clamp`), never
mid-line.
- Dynamic bar subtitle: the now-playing / archive programme title instead of a
static "Timeline" label.
- State-aware toolbar: hide Now + zoom when there is no ribbon, and the date
stepper when the channel has no EPG on any day (hidden, not disabled).
- Empty-state fills and centres within the panel area instead of a fixed
min-height that overflowed the compact inline panel and hid the buttons.
EPG current-programme lookup (electron-backend)
- Timezone-aware "airing now" comparison via SQLite `datetime()` (was a lexical
string compare that broke for offset vs UTC `Z` timestamps).
- Unscoped fallback for resolved candidates whose programmes are tagged with an
out-of-scope source (multi-source imports sharing XMLTV ids), so the sidebar
matches the timeline.
- Match channel candidates by the raw (case-sensitive) key as well as `LOWER()`,
since SQLite `LOWER()`/`COLLATE NOCASE` fold only ASCII — fixes Cyrillic /
Greek channel names showing "No program information available".
- Overlap-based day membership (`hasProgramsForDateKey`) so a film spanning
midnight keeps the ribbon on "today" while it airs.
Refactor
- Extract the duplicated channel-list EPG enrichment (progress + side-car map)
into `channel-list-container/epg-enrichment.util.ts`, shared by the
all-channels / groups / favorites / recent views; also fixes recent's and
favorites' unguarded, NaN-prone progress maths.
Tests: ui-epg 75, components 77, electron-backend 432; lint + web build green.

Swap M3 primary palette from violet to azure so checkboxes, radio
buttons, raised CTAs, and active states read as the same blue used by
the rail selection token. Cascading template + SCSS updates align the
remaining hand-rolled surfaces (Add Playlist dialog, VOD play button,
radio player, multi-EPG, empty-state CTAs) with the unified system.
LIVE stays red (broadcast role), cyan stays on EPG "now" indicator,
green stays on completed-download — semantic colors keep their meaning;
only the indiscriminate accent uses get folded into the blue primary.
