The Browse tab nav scrolled away (operator didn't know it existed) and Posts had no search. Roll the tab strip + a shared search field into one sticky block pinned under the 64px TopNav. - Posts gains server-side text search: PostFeedService.scroll()/around() + /api/posts accept q (ILIKE over post_title OR description), applied INSIDE the artist/platform WHERE so search stays scoped to the active filter. Scope shown as clearable chips next to the search field. - Artists/Tags search consolidates into the sticky bar: their inner search boxes are removed; they react to route.query.q (q is deep- linkable, e.g. /browse?tab=posts&q=foo). Platform/kind filters stay. - Posts empty state now distinguishes 'no matches' from 'no posts yet'. Tests: posts q-search matches title|description and stays artist-scoped (service); q passthrough (api). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
