/* Rally HQ Blueprint Prototype — Shared CSS
 *
 * Ports Midnight & Indigo tokens from Rally HQ DESIGN.md into a
 * standalone stylesheet so prototype HTML renders without the SvelteKit app.
 * (System renamed from "Midnight & Copper" 2026-05-26 — there is no copper
 * hue in the palette.)
 *
 * Deviations from shipped (per blueprint/DESIGN-PRINCIPLES.md):
 *   - Space Grotesk as display font (was: Sora-for-everything)
 *   - JetBrains Mono for data atoms (court numbers, times, seeds)
 *   - --tournament-accent CSS variable per-tournament override
 *   - LIVE pulse component (new)
 *   - Action-overlay pattern (new)
