/*
 * The public site's stylesheet (CASH-85).
 *
 * Hand-written, and deliberately not Tailwind. The application compiles Tailwind
 * because it is thousands of utility classes across fifty templates; this is two
 * pages whose classes were already hand-written rules in the app's stylesheet.
 *
 * ---------------------------------------------------------------------------
 * The token block below is the one thing shared with the application, and it is
 * shared by copy rather than by import — the two surfaces deploy separately and
 * an import would put the app's build on the static site's critical path, which
 * is exactly the coupling this module exists to remove.
 *
 * It is a curated subset: the palette, the type scale and the two control
 * tokens. It is not the app's @theme block. If a colour changes in
 * app/src/main/css/app.css it must be changed here too, and that is the
 * accepted cost of the split. Keep this list short so that stays true.
