/* CECloud Web Design System — component library CSS
 * One class per component (`ds-*`), styled purely from the token custom
 * properties. The React components in components/ render these classNames;
 * guideline cards and UI kits may use the classes directly.
 * Signature details from the theme's business-page CSS:
 *   - buttons carry a 2px bottom shade — express alpha as
 *     color-mix(in srgb, var(--primary-6) 10%, transparent); never rgba(var(--x-6), a),
 *     because the palette tokens are already complete rgb() values and nesting them
 *     in rgba() makes the browser drop the whole declaration
 *   - focus ring 0 0 0 2px primary-1 on inputs/selects
 *   - alerts use a 336deg gradient wash + bottom shade
 *   - tables have rounded 8px headers and no outer border
 *   - drawers/modals float with 8px radius */
