/* TRAX guide — standalone stylesheet.
   The app's `surface-*` / `primary-*` Tailwind classes resolve to `var(--p-*)` variables that
   PrimeVue emits at runtime, so they are unavailable here. The tokens below are the resolved
   values of the Aura preset configured in cmd/client/src/main.ts: primary = sky, secondary =
   amber, light surface = slate, dark surface = zinc. Dark mode is prefers-color-scheme only,
   matching PrimeVue's `darkModeSelector: 'system'`. */
