 Also open (from the quality review): a real `onError`/error-state fallback for iframes that fail to load (deleted post / region lock / X login-wall) — cross-origin frames don't fire `onError` reliably, so this needs a load-timeout heuristic; the Close button + badge link are the current escape hatch.
 
+**✅ Steam detailed embed (2026-07, 2-agent review) — `ef82650c`.** `store.steampowered.com` content URLs get rich cards: **app** pages → OG capsule header + click-to-play facade → Steam's official `/widget/{id}` store iframe (live region-aware price / discount % / Buy on Steam, gated by `inlineMediaEmbeds`); **news/announcement** → banner + headline + body-preview card; **bundle/sub/dlc** → OG store card. `getSteamTarget`/`steamWidgetEmbedUrl` in `videoEmbed.ts` (+tests). Grounded in prod CSP (`frame-src https:` allows the widget with no infra change; images via homeserver `mxc`; NO client-side Steam API — `connect-src` + Steam CORS both block it, which is the honest ceiling: no review scores/genres/screenshots client-side). **Needs on-device QA:** the live widget iframe height/fit (can't render headlessly) — verify the price/Buy stay visible on desktop-wide and phone.

 **✅ Embed bug hunt (2026-07, 3 survey agents + 2-agent review) — `f2673eff`.** Core posture verified **sound** (iframe sandbox, `useIframeAutoHeight` postMessage origin+source trust, no XSS/`dangerouslySetInnerHTML`, `rel="noreferrer"` on all 21 links, oEmbed no-SSRF, the whole facade→iframe/abort/observer lifecycle). Fixed: Twitch/Kick/SoundCloud/Streamable reserved-path over-match (utility pages rendered as broken players), Vimeo hash over-capture (`[0-9a-f]{6,}`), Spotify/Steam/Discord/IMDb `og:image` now via `mxcUrlToHttp` (was a broken raw `mxc://` `<img>` + a pre-click 3p-request facade bypass), `wide` class follows the og:url-resolved embed, Twitter host alignment (`mobile.twitter.com`/`/statuses/`), URL de-dupe.
