/* ============================================================
 * rustio-admin / tokens / shadows
 *
 *   === Tokens — shadows ===
 *
 * Shadows remain deliberately quiet — premium tooling prefers
 * borders + surface contrast over drop shadow. v0.15.0 bumps the
 * default-shadow alpha so a card actually rises off the canvas at
 * arm's length (the prior 0.05 was invisible on the new deeper
 * `--rio-bg`). The shadow scale also gains a `--rio-shadow-inset`
 * variant used by inputs and pressed states.
 *
 * The two-layer construction (one tight near-shadow, one wider
 * far-shadow) follows the Stripe / Linear convention — crispness
 * up close, lift from a distance.
 * ============================================================ */

:root {
  /* v0.16 — slightly lighter alpha. With the new white-card-on-
   * lighter-canvas relationship, heavy shadow over-states card
   * lift. The two-layer construction stays (Stripe / Linear / Vercel
   * convention — tight near-shadow for crispness, soft far-shadow
   * for lift). */
