/*
 * Global design system for St. George United.
 *
 * Bright, energetic sports-academy palette (temporary — every important
 * value is a custom property so the official brand palette can be
 * substituted later without touching component code). The footer keeps a
 * deliberate dark-navy surface as a contrast anchor; it uses its own
 * dedicated tokens (--surface-footer*, --footer-text*) rather than the
 * light-theme text/surface tokens, so it stays legible after the palette
 * flip below.
