   CONNECT (SOCIAL) PAGE -- Claude Design reskin
   Ported from the "unQbd Connect social feed" design. Self-contained:
   every class here is Connect-only (SocialFeed is used only by the
   Connect page). The post CARD internals are NOT here -- they live in
   the shared SocialPostCard / user-profile.css and are left untouched;
   this file styles only the page chrome, feed wrapper, and feed states.
   --soc-* tokens resolve from brand-tokens.css with safe fallbacks.
   Dark mode is handled via body.dark-mode (never prefers-color-scheme).
