/* ==========================================================================
   CSS architecture map
   --------------------------------------------------------------------------
   This file still contains historical design passes. Current maintenance work
   should be staged: prefer comments, admin scoping, and final guards before
   deleting cross-media overrides. High-risk areas: brand header, mobile action
   bar, prompt output, privacy notices, legal pages, and admin visibility.

   Current sections:
   - Tokens and base reset
   - Layout and shell
   - Components and form controls
   - Historical design passes
   - First-run UX / accessibility helpers
   - Legal pages
   - Late product polish
   - Final production guards
