web: iOS 26 Liquid Glass redesign of the embedded UI (v1.0.0)
Reskin the embedded PWA from the dark "crosspost console" into a light,
native-feeling iOS 26 (Liquid Glass) app, from a Claude Design handoff.
- New light token system (indigo/teal accent) + system SF type; existing
CSS variables remapped so every tab adopts the new palette.
- Glass top brand bar + glass bottom tab bar (SF-style icons).
- Compose: composer card (avatar/author/footer), target rows with brand
tiles, live per-platform counts, iOS switches, and a thread badge;
auto-thread notice banner + glass thread-review sheet (numbered
timeline). Live preview gains brand tiles, platform-tint token
highlighting, and a numbered thread timeline (via /api/thread-preview).
- New brands.js (platform tints, brand glyphs, UI icon set) + extracted
Threads/Nostr mark PNGs under assets/marks.
- manifest: light theme/background colors; standalone display retained.
- All DOM ids/classes the JS queries are preserved; embed test extended.
