   Rules of the system (mirrors hub.css — the approved AI Catalyst mockup):

     • Catalog-rail selected state = mint tint + bold ink + teal check +
       3px teal left edge; results filter strip = forest-filled active pill.
     • DM Mono for kickers/labels/meta; Newsreader for display headings.
