/* ===========================================================================
   Shared dark design system.

   Colour tokens arrive as custom properties from brands/<slug>/brand.toml,
   injected into the <head>. This file is identical for all four storefronts
   and never needs a per-brand build.

   Token contract:
     --bg-deep --bg --bg-elevated --border
     --text --text-muted
     --primary --primary-hover --primary-contrast
     --accent --accent-contrast
     --success --warning --danger
     --hero-from --hero-to
     --font-heading --font-body

   Layout-specific rules live in layouts.css. Anything added here is shared by
   all four brands, so think twice before putting something here that only one
   of them uses.
