   Two modes, one system:
   - Automation mode (default): blueprint navy, circuit teal
   - Travel mode (.travel, used on the Yatrika page content):
     sand paper, route gold, map teal, pin coral
   Nav + footer stay in automation ink everywhere — the
   constant "frame" both projects ship inside.
