   SEAMLESS OPS — Shared Styles
   ----------------------------------------------------------------------------
   WHAT: Brand tokens + chrome (topbar/sidebar) + base components used across
         every module page.
   WHY:  Mirrors the customer-portal navy/red palette so the ops app feels
         like part of the same family. Tokens live in :root so a future
         re-skin is one block of edits.
