Subject: [PATCH] [playback] Add HLS support and stop blaming stale MediaErrors

bitvid attached every hosted source with `videoEl.src = url`, which only plays
HLS on Safari-family browsers. Firefox 146 fails with MEDIA_ERR_SRC_NOT_SUPPORTED
(canPlayType returns ""), so every .m3u8 note -- e.g. anything published by
nostube/slidestr -- was unplayable there and the URL-health badge showed
"offline". Chrome/Brave 149 happen to play HLS natively, which is why this
looked browser-specific.

Vendor hls.js (npm run build:hls) and route HLS sources through it:

- js/services/hlsPlayback.js owns detection, engine choice and the hls.js
  lifecycle. Engine choice keys off MediaSource, NOT canPlayType: Chrome
  returns "maybe" for every HLS type, so a native-first branch would hang.
  Native is used only when MSE is genuinely unavailable.
- The bundle is the FULL build, not hls.js/light -- light drops the alternate
  audio stream controller and real ladders demux audio into an EXT-X-MEDIA
  group. It is lazy-imported only when a .m3u8 is encountered, so ordinary
  MP4/WebTorrent playback never pays the ~500KB.
- modalCoordinator tears the instance down first; clearing `src` alone leaves
  the transmuxing worker and segment fetches running after the modal closes.
- urlHealthController probes HLS by fetching the playlist for #EXTM3U. The old
  bare-<video> probe could not load it and on Chrome emitted no events at all,
  burning the full timeout on every HLS card.
- HLS_PLAYBACK_START_TIMEOUT widens the 3s start window, which fired
  mid-startup: the bundle, master playlist, variant playlist, init segment and
  first media segment are four-plus serial round trips.

Also fixes two bugs found while verifying this:

- A stale MediaError was reported as the current failure. Teardown clears `src`
  and calls load(), leaving MEDIA_ERR_SRC_NOT_SUPPORTED ("Empty src attribute")
  on the element; a later watchdog fallback rendered that as "Hosted playback
  failed: source not supported or blocked." over a stream that was playing
  fine. Only a MediaError produced by the current attempt is surfaced now.
  Sources are also bound before the watchdogs are armed, so hls.js's own
  attachMedia() src swap cannot read as a playback failure.
- `audio/x-mpegurl` is a legacy alias for an HLS playlist of any kind, not an
  audio-only assertion. isAudioOnlyVideoObject misfiled HLS video ladders
  published with it as podcasts and dropped them from every video feed.

Verified end-to-end in Chromium, Chrome 149, Brave 149 and Firefox 146 against
a live HLS stream: Firefox goes from "No playable source found." to playing.
Rollback: stop calling attachHlsSource() and the previous `src` assignment
returns; see docs/playback-fallback.md.

+## HLS (.m3u8) sources
+
+Hosted sources whose path ends in `.m3u8` are HLS playlists and cannot be
+assigned to `videoEl.src` on every browser. `js/services/hlsPlayback.js` owns
+the decision and the hls.js lifecycle.
+
+**Engine choice.** hls.js (MSE) wins whenever `MediaSource` can back it; native
+playback is used only when MSE is unavailable. Do NOT branch on `canPlayType`
+alone — measured behavior differs sharply:
+
+| Browser | `canPlayType("application/vnd.apple.mpegurl")` | bare `<video src=…m3u8>` |
+| --- | --- | --- |
+| Firefox 146 | `""` | `MEDIA_ERR_SRC_NOT_SUPPORTED` (code 4) |
+| Chrome 149 | `"maybe"` | plays natively |
+
+Before this existed, Firefox reported `No playable source found.` for every HLS
+note (and the URL-health badge showed `❌ CDN`), while Chrome happened to work.
+
+**Wiring.**
+
+- `js/services/playbackService.js` — `attemptHostedPlayback` routes HLS
+  candidates through `attachHlsSource()`; `resetVideoElement()` calls
+  `detachHls()` before clearing `src`.
+- `js/app/modalCoordinator.js` — `teardownVideoElement` calls `detachHls()`
+  first; otherwise the transmuxer worker and segment fetches outlive the modal.
+- `js/ui/urlHealthController.js` — probes HLS by fetching the playlist and
+  checking for `#EXTM3U` instead of using a bare `<video>` (which cannot load it
+  and, on Chrome, emits no events at all — burning the whole probe timeout).
+- `HLS_PLAYBACK_START_TIMEOUT` (`js/constants.js`) widens the 3s start window,
+  which fires mid-startup for HLS: the bundle, master playlist, variant
+  playlist, init segment and first media segment are serial round trips.
+
+**Vendoring.** `npm run build:hls` regenerates `vendor/hls.bundle.min.js` from
+the pinned devDependency. It is the FULL hls.js build, not `hls.js/light` —
+light drops the alternate-audio stream controller, and real ladders (e.g.
+nostube/slidestr) demux audio into its own `EXT-X-MEDIA` rendition group. The
+bundle is lazy-imported only when an HLS URL is encountered, so ordinary
+MP4/WebTorrent playback never pays for it.
+
+**Rollback.** Stop calling `attachHlsSource()` from `playbackService.js` /
+`playbackCoordinator.js` and the previous `videoEl.src = url` behavior returns;
+revert the `urlHealthController.js` branch to restore the old element probe.
+Nothing else imports `hlsPlayback.js`, and the vendored bundle is inert once
+unreferenced.
+
 ## Implementation notes
 
 - The playback session is responsible for cleanup and emits events (`status`, `sourcechange`, `error`, `finished`) that `bitvidApp` listens to for UI updates.
 - `bitvidApp.playVideoWithFallback` keeps the current video card and modal state in sync with the normalized magnet values so copy actions and stats reflect the actual playback payload.
 
+
+## Link previews (NIP-92 imeta + per-video OpenGraph)
+
+Two independent surfaces make a shared bitvid video render richly.
+
+**1. Inside nostr clients — `js/nostrEventSchemas.js`.**
+`buildShareEvent()` appends a NIP-92 `imeta` entry describing the thumbnail URL
+that the note body ends with. Many clients only inline such a URL when an imeta
+entry backs it; without it the viewer sees a bare link. The media type is
+inferred from the extension (`inferImageMimeTypeFromUrl`, `js/utils/mime.js`)
+and OMITTED when unknown — a wrong `m` is worse than a missing one, because
+clients use it to decide whether to render inline at all. Extensionless
+Blossom-style URLs therefore ship `url` + `alt` only.
+
+**2. Everywhere else — `api/og.js` + `api/_lib/ogRenderer.mjs`.**
+`index.html` carries one set of site-wide OG tags, so every `/?v=<nevent>` link
+previewed as the same generic card. Crawlers don't run JS, so this is rendered
+server-side on demand.
+
+- **Nothing is pre-generated or stored.** One stateless function serves all
+  videos; the video is a query param, not a path. `dist/` is byte-identical
+  with or without it. The only caching is the CDN edge (`s-maxage=300`) plus a
+  per-container in-memory memo of the admin lists.
+- **Never load-bearing.** Only crawler user-agents are rewritten to it
+  (`vercel.json`), humans get the untouched SPA, and a static/nsite deploy with
+  no functions keeps working — it just serves the site-wide card. Rollback is
+  deleting the `rewrites` block.
+- **Player card, not just an image.** It emits `twitter:player` / `og:video:url`
+  pointing at `embed.html?pointer=<nevent>`, so a shared link plays inline on
+  Twitter/Discord/Telegram. `frame-ancestors *` (`_headers`) already permits it.
+- **Fails closed.** A crawler never authenticates, so anything emitted is public
+  forever in third-party caches. `isPubliclyShareable()` requires an
+  affirmatively public video: `deleted`, `isPrivate`, `isNsfw`/`content-warning`,
+  blacklisted authors, and — while whitelist mode is on — an unavailable or
+  empty whitelist all fall back to the generic card.
+- **Both event shapes.** `parseVideoEvent()` reads bitvid's kind-30078 v3 JSON
+  AND the NIP-71 tag shape (kinds 21/22/34235/34236) that nostube/slidestr
+  publish, where the title lives in a `title` tag and the thumbnail in an
+  `imeta image` entry.
+- **Timeouts.** A cold pool's first relay read measured ~3s, so the budget is
+  4s (Twitter allows ~5s); warm containers answer in <600ms because the admin
+  lists are memoized for 5 minutes.
+
+Config is imported from `js/config.js`, `js/nostr/toolkit.js` and
+`js/nostrEventSchemas.js` rather than duplicated, and `tests/og-renderer.test.mjs`
+fails if that regresses to hardcoded literals.
+
+### Quoting the NIP-71 mirror
+
+When a video has a NIP-71 mirror, the share note embeds `nostr:naddr1…` for it.
+Nostr clients render that as a **native video quote card** — the closest thing
+to a rich preview that does not depend on any client fetching OpenGraph tags
+(most never do; the OG endpoint above mainly serves Twitter/Discord/Telegram).
+
+The mirror is addressable (kind 34235/34236, author = video pubkey,
+`d` = `videoRootId`), so `js/nostr/mirrorPointer.js` derives the coordinate with
+no relay lookup, and the pointer survives the author editing the video — a plain
+`nevent` would rot on the next replace.
+
+Rules that keep this from looking worse than the plain link:
+
+- **Verify before pointing.** `ShareNostrController.resolveMirrorPointer()`
+  confirms the mirror exists via `nip71MirrorService.findMirror()` before
+  embedding anything. A pointer to a missing event renders as a broken/empty
+  quote box. Every failure path — service disabled, lookup throws, lookup times
+  out (2.5s), no `videoRootId` — falls back to the thumbnail-URL note.
+- **Use the observed kind.** `resolveMirrorKind()` prefers the kinds actually
+  seen on relays over the portrait heuristic. Only when nothing was observed does
+  it fall back to the SAME rule the mirror builder uses (`nip71Mirror.js`:
+  `hasDims && height > width`), so a derived pointer matches what would be
+  published rather than guessing independently.
+- **Never emit both images.** While quoting, the raw thumbnail URL is dropped
+  from the body and the `imeta` tag is skipped — the quote card already shows the
+  thumbnail, and keeping both rendered the same image twice.
+- An `a` tag (`kind:pubkey:d`) links the note to the quoted coordinate for
+  quote-aware clients and indexers.
+
+Known limitation: a client rendering the quote card still needs to play the
+video, and mirrors whose `imeta url` is an `.m3u8` hit the same HLS wall bitvid
+did — the thumbnail and title render, playback depends on the client.
