 *           ↓
 *   styles/tokens.css
 *           ↓
 *   HRD-Mobile Web UI
 *
 * src/config/design-tokens.js remains authoritative. This file maps the
 * existing semantic tokens to CSS custom properties only — it introduces no
 * new product semantics, no component styling, and no business rules.
