/* ==========================================================================
   Selcom Brand Hub — Stylesheet
   Design language: "control room for the brand" — a calm, dark utility
   shell with a bright signal-orange accent used sparingly, so the assets
   and guideline colors displayed *inside* the app are what stand out, not
   the chrome around them.

   NOTE ON COLOR: --brand-accent is a placeholder (#FF5A1F). Swap it for
   Selcom's real primary hex the moment you have it — it is the only color
   referenced by name below and touches nothing structural.
