   DTS brand kit — "The Shop Floor" (redesign 2026-10-19)
   Built from the logo (orange #F5870F / teal #0A7088), the shop, and our
   calibration screens. Plan: docs/business/DTS_REDESIGN_PLAN.md

   SCOPING RULES (so this file can sit beside dm-port.css on the homepage):
     .dts-nav / .dts-foot  — site chrome, global, self-contained
     .dts2 …               — every other rule is scoped under body.dts2
   The homepage keeps dm-port.css for its body; it loads this file ONLY for
   the chrome. Never add an unscoped rule here.
