/* Shadow tokens
 * Static file — NOT generated by npm run tokens.
 * Shadows cannot be exported as DTCG variables from Figma, so these are
 * transcribed by hand from the Figma effect styles.
 *
 * Naming: --ao-shadow-{2xs|xs|sm|md|lg|xl|2xl} plus two component-specific levels
 * (card, cc-rail).
 *
 * Source of truth: the `shadow/*` effect styles in the Design System file
 * (Lus07xi8pPXLN87sQIyrEt, range frame `3730:26393`). The designer redefined the
 * whole family on 2026-09-23 as a seven-step scale; it replaces the previous
 * `light/shadow-*` / `dark/shadow-*` styles and the old xxs/base/sm/md/lg ladder.
 * Last synced from Figma: 2026-09-23.
 *
 * Every layer is pure black at one of two alphas:
 *   #0000000D = 0.05 (2xs, xs)      #0000001A = 0.10 (sm → 2xl, both layers)
 *
 * Layer order matches the order Figma lists the effects, so a future style diff
 * reads straight across.
 *
 * Migration from the old ladder (2026-09-23):
 *   xxs  → 2xs    base → sm    sm → sm    md → md    lg → xl  (consumers re-pointed)
 * The old lg's consumers (modals, panels, popovers) moved to xl rather than the new
 * lg, so they keep a clear step above md's menus and tooltips — judged side by side
 * before the change.
