/*
 * UnlimitedModel.com — User Dashboard design system
 *
 * The ADMIN backend (styles/admin.css, .admin-shell) is the design-system
 * reference for every authenticated surface. This file mirrors its token
 * values verbatim (warm canvas #f7f7f5, white surfaces, #e7e5e4 borders,
 * 236px sidebar, 60px topbar, 28px page padding, 22px stack gap) scoped to
 * the user dashboard root (.user-shell on #page-dashboard in index.html).
 *
 * Role changes CONTENT, never visuals: nav items, cards, tables, buttons,
 * badges, forms, empty/loading states and responsive behavior here use the
 * exact same measurements and colors as .admin-shell.
 *
 * Load order: theme.css → tokens.css → app-shell.css → base.css →
 * components.css → components-modals-dropdowns.css → pages.css →
 * landing.css → user-dashboard.css (last, replacing the cascade slot the
 * old migrated landing.css dashboard block held).
