/*
 * UnlimitedModel.com — Backend App UI (ONE component layer)
 *
 * The user dashboard (.user-shell) and the super admin (.admin-shell) are the
 * SAME shell: 232px sidebar · 60px topbar · 24px page padding · one card, one
 * button, one input, one table. Every rule below is scoped to both shells at
 * once so the two backends can never drift apart again.
 *
 * This file owns the shell, navigation, topbar, page header, stat cards,
 * tables/toolbars/pagination and the empty/loading surfaces. Page-specific
 * content stays in user-dashboard.css / admin.css; generic controls (button,
 * input, card, modal, toast, badge) stay in components.css.
 *
 * Load order: tokens → app-shell → base → components →
 * components-modals-dropdowns → app-ui → pages → landing → user/admin.
 *
 * No !important. No negative margins. No magic offsets: every measurement
 * comes from a token or is a documented component dimension.
 */
