/* ==========================================================================
   Preview canvas styles. Two layers of custom properties, both set at runtime
   by js/applyTokens.js on #deviceFrame:

     1. Globals   --color-*, --radius-*, --space-*, --text-*, --shadow-*, --font-*
     2. Component --cmp-<name>-<prop>  (each ALWAYS resolves to var(--a-global-token))

   Every rule below reads --cmp-* first when a component-level config exists in
   js/componentRegistry.js, and falls back to a global token directly for parts
   of a component that aren't (yet) independently configurable. This is what
   makes a component's look editable from its own config panel without ever
   letting it hold a value outside the token system.
