/* ---- Design tokens (ARCHITECTURE.md §3.2) -----------------------------------------------------
   The shared vocabulary both sites size, space and color themselves from. Loaded by every host
   before its own app.css, so a host still wins where it deliberately disagrees.

   PURELY DECLARATIVE. There is not one element selector in this file, so adding the <link> changes
   nothing on screen until something asks for a token. That is what lets this ship ahead of the
   screens that use it.

   --cv-, NOT --carvin-. The Portal's own app.css already defines --carvin-ink, --carvin-accent and
   five more on :root, and it loads after this file - so reusing that prefix would have this layer
   silently overwritten on one of the two sites it exists to unify.

   LIGHT AND DARK, and nothing else. The host stamps data-carvin-scheme on <html>; a component may
   not ask which theme is running, because AppTheme lives in a module and shared UI may not
   reference one (FRAMEWORK.md §3.3). An attribute is the whole interface. */
