/* AdvisorCal design system — Steward & Heir editorial finance aesthetic.
 *
 * Originally a warm-professional cognac palette (April 2026 handoff). As of
 * the Steward & Heir redesign (May 2026, Phase 8), the `--ac-*` tokens are
 * now mapped to Steward values so every existing surface that uses the
 * `.ac-*` classes inherits the new aesthetic without component-level edits.
 * The `--ah-*` block below holds the canonical Steward token set; the
 * `--ac-*` block here is a compatibility bridge.
 *
 * Load via <link rel="stylesheet" href="/design/tokens.css">. */
