   NACHRICHTEN v3 — the office↔driver line.

   The page is src/features/chat/chat.page.ts →
   public/js/pages/chat.js; this sheet holds every .ch3-* rule.
   Token-native under .mt-scope — dark mode is a token swap, never a
   parallel rule set. The driver PWA's .chat-* rules live in its own
   sheet and are unrelated. Two panes; on the phone one at a time
   (.has-room slides the list away).
