/* OpenCloudBox hosted console — documented UI system (visual-only).
 *
 * Tokens and components used by apps/web/src/views.ts:
 * - Spacing/type tokens: --space-*, --radius-*, --shadow, h1/h2 scale.
 * - Layout: .page-head, .breadcrumb, .subnav, .grid-2, .lifecycle-bar.
 * - Surfaces: .card (.card--hero), .table-wrap + table.table, .pill, .kv.
 * - States: .state (+ .state--error), .empty (+ .empty-icon), .skeleton.
 * - Utilities: .mono, .numeric, .truncate, .lede, .eyebrow, .footer-note.
 * - Legacy aliases kept for compatibility: .list, .meta, .badge, .notice,
 *   .actions, .button, .danger, .skip, .state.
 * Color values are unchanged from the AA-passing baseline; new accents reuse
 * the audited accent/badge/danger ramps only. See docs/t19-web-console-ui.md.
