/* Design tokens — source of truth: docs/mockups/README.md
 *
 * Mockup-aligned names are primary. Legacy alias names (--bg-card, --border,
 * --text-secondary, --warn) are kept so existing component <style> blocks
 * keep working without a churny rename. New components should use the
 * mockup names.
 *
 * Dark mode was removed in Phase 1 — the mockup is intentionally warm/light
 * (luxury feel, warm copper accent). A `prefers-color-scheme: dark` media
 * query was previously flipping the accent to near-white, which conflicts
 * with the warm-copper intent. Re-add as a separate ADR if dark mode is
 * needed; for now, one intentional palette beats two half-baked ones.
