/* Shared shell for the `main` and `portal` layouts.
 * Design tokens + chrome (reset, body, header, language switch, alerts,
 * footer) that were previously duplicated in main.css and portal.css.
 * The `landing` layout has its own palette and is intentionally NOT based
 * on this file. Each layout links base.css first, then its own overrides.
 *
 * Token set is the portal superset; main only consumes a subset (the extra
 * tokens are harmless when unused). */
