/* =====================================================================
   Dealer portal — page BODY design system (tokens + components)

   Opt-in per page: <body class="mt-body"> + this stylesheet, linked AFTER
   dealer-dark-mode.css. Scoped to <main> and the page's modals/toasts only —
   the shared header, nav and footer are untouched.

   Restrained, neutral, enterprise look: Inter, neutral grays, 1px borders,
   6 / 8 / 10 / 12px radii, no shadows on static surfaces. Values match the
   Team Portal's token set (css/team-theme.css); the accent is the dealer
   portal's own brand blue (#006897, as in the dealer header).

   In use on: dealer-billing.html, dealer-invoice-detail.html
