/* Mobile primitive layer.
 * This stays separate from desktop primitives and sets the baseline for:
 * - auth shell pages
 * - staff mobile dashboard shell
 * - shared mobile typography/controls
 *
 * Later phases should move page-specific `staff-*` and `app-auth-*` styling
 * toward this layer rather than inventing new component families.
