/* ── Creative Diversity Matrix — standalone app shell ──────────────
   Deliberately its own small stylesheet, not dashboard.css's topbar/
   kpi-bar/tabs system. Reuses dashboard.css's --color-*/--space-*/
   --radius-* tokens (linked alongside this file) for theme + dark-mode
   consistency, but every layout/component rule here is purpose-built for
   this page — see SPEC_creative_diversity.md §11. Most component styling
   lives as inline styles in js/ui/diversity.js's render functions (matching
   this codebase's existing convention); this file only covers what inline
   styles can't do well (hover states) and the page shell itself. */
