/* ─────────────────────────────────────────────────────────────────────────
 * PRISM — Universal Design System
 *
 * One file, every page. Every operator-facing module loads this BEFORE its
 * own page styles. Page-specific CSS only adds — it never overrides tokens.
 *
 * Architecture rules:
 *   1. All color, type, spacing comes from --tokens defined in :root
 *   2. Components are .prism-* classed; their internals follow BEM-ish naming
 *   3. Mobile-first: base styles work at 375px; media queries expand upward
 *   4. No magic numbers in components — only --tokens
 *
 * Pair with prism-shared.js (which renders the header + Herb pill globally).
