/* ============================================================================
 * SipNudger hydration ring gauge — THE canonical stylesheet.
 * ----------------------------------------------------------------------------
 * This file is the single source of truth for the gauge and the readout panel
 * around it. It is plain CSS (not SCSS) on purpose, so the same bytes can be
 * used by two very different consumers:
 *
 *   1. the Vue app  — imported by src/components/HydrationRing/index.vue
 *   2. the static marketing pages — served as /gauge.css and <link>ed by
 *      infra/nginx/marketing/index.html and demo.html
 *
 * The marketing copy is GENERATED by infra/scripts/sync-gauge-css.sh; never
 * edit it by hand. `sync-gauge-css.sh --check` fails the deploy if the copy has
 * drifted from this file, so the two cannot silently diverge.
 *
 * The device's LED ring (esp32/IoT/main/led-display.cpp) follows the same
 * colour language — aqua arc for progress, amber marker for the pace position —
 * but cannot share code with a stylesheet.
 *
 * Tokens (--surface-1, --accent, --text-1, …) come from identity.scss in the
 * app and from the :root block in each marketing page. Both define the same
 * names, which is what lets this file be shared.
 * ==========================================================================*/
