/* Roote Shule design tokens.
   Every colour, size and timing used by the web app, the public site and
   printed documents. Schools override the four --school-* inputs; everything
   else derives from them. Production emits computed hex values from the
   server (ThemeTokens) so PDFs and the Flutter app get the same numbers. */
