/* =========================================================================
   addressable.wiki
   Hand-written, no framework. Tokens are documented in /design.md.

   Theming contract: the complete palette is defined on bare :root (light).
   Dark overrides only the tokens, twice — once under prefers-color-scheme for
   the default "system" state, once under [data-theme="dark"] so an explicit
   toggle wins in both directions. No colour is ever defined ONLY inside a
   media query.
