   Visual direction: an analog broadcast console, not a generic SaaS panel.
   Tally-light orange for the primary signal, teal for patch-cable accents,
   mono type for anything that reads like a live readout (labels, stats,
   ids), Space Grotesk for nameplates/headings, Inter for body copy.

   This file is shared by the homepage, account picker and dashboard.
   Class names referenced by client-side JS in server.js (.nav-item,
   .tab-content, .card, .dropdown-item, .feed-item, .editor-row, etc.)
   are preserved exactly — only their appearance changes here.
