/* ── Priszim marketing site — PRISM-NOIR design system ─────────────────────
 *
 * Palette carried from the approved 2026-07-05 design spec
 * (docs/superpowers/specs/2026-07-05-marketing-website-design.md).
 * Reconcile against docs/design/PRISM-NOIR.md once feat/w6-prism-noir merges.
 *
 * Binding rules:
 *   - beam teal (--beam) is for TEXT, LINKS, FOCUS only — never a large fill
 *   - deep teal (--teal-fill) is for FILLS only — never text (fails AA)
 *   - spectrum colors are identity moments only, NEVER money figures
 *   - ONE beam-glow chart per page; ONE ambient glow per page
 *   - prefers-reduced-motion collapses all motion
