From the second review pass (agents inspected providers' live embed scripts):
- FIX Reddit auto-height (was broken): embed.reddit.com posts
{ type:'resize.embed', data:<height> } — height is under 'data', not 'height',
so it never resized and clipped taller posts (scrolling=no). Add that shape.
- Align TweetEmbed sandbox with EMBED_SANDBOX (adds allow-popups-to-escape-sandbox)
so links/login popups opened from inside a tweet aren't crippled.
- Vimeo: resolve channel/group/album video forms (vimeo.com/channels/{n}/{id} etc.),
not just paths starting with the id.
- Mobile Shorts: m.youtube.com/shorts/{id} now renders portrait 9:16, not landscape.
- Move extractEmbedHeight into videoEmbed.ts and unit-test all three resize shapes
(Instagram MEASURE / Reddit resize.embed / Twitter twttr.private.resize).
Agents confirmed everything else current & robust (Dailymotion geo host, Tidal
gridify, sandbox tokens are a safe superset, X still on platform.twitter.com,
550px cap). Tests 21 in this suite.
