 * AIZEN design tokens — the single source for brand values.
 * Source: AIZEN Mobility Brand Guidelines, version 1.0 (August 2026).
 *
 * Cascade layers, lowest priority first:
 *   aizen-tokens      these custom properties
 *   aizen-base        shared element defaults (base.css)
 *   site-base         a site's own element resets: write `@layer site-base { a { ... } }`
 *   aizen-components  shared az-* components (components.css)
 *   (unlayered)       everything else in a site's stylesheet, which therefore
 *                     overrides shared components and tokens on purpose.
 * Keep bare element selectors (a, button, svg ...) in site-base so they never
 * restyle shared components by accident. Prefer semantic tokens (--az-color-*)
 * in site CSS; palette tokens exist for brand moments.
