   CCCom Theme System (Layout + Color) – FULL FILE
   =====================================================================================================================

   QUICK CLASS / SELECTOR INDEX (use these in your markup)

   Root selectors (set by JS):
   - :root[data-cccom-layout="formal|relaxed|compact|modern|artsy"]     => layout theme (spacing, radius, typography, control sizing)
   - :root[data-cccom-color="light|dark|cccom-blue-dark|vt320-green-dark|vivid|high-contrast-more|hc-light|hc-dark"] => color theme
   - :root.cccom-reduced-motion        => disable animations/transitions (host sets)
   - :root.cccom-high-contrast-more    => stronger focus ring (host sets)
   - :root.cccom-forced-colors         => yield to OS forced colors (host sets)

   Global container / surfaces:
   - .cccom-ui            => wrap a subtree that should use the CCCom design system
   - .cccom-card          => elevated card (primary surface)
