+## Design system (gnexus-ui-kit v1.0)
+
+Full component docs, rules and demo live in the vendored copy:
+**`vendor/gnexus-ui-kit/CLAUDE.md`** — read it before styling anything.
+
+Facts specific to this app:
+
+- Kit is consumed as **prebuilt CSS**: `import 'gnexus-ui-kit/css'` in `src/main.js`
+  (kit v1.0's `_fonts.scss` references fonts by relative url(), which breaks
+  Sass source compilation — the Vite bundler resolves them instead).
+- **Theme**: default dark `dist/css/kit.css`. No theme switcher.
+- **Tokens**: CSS variables `--gn-*` (colors/surfaces/borders/motion/spacing)
+  everywhere in styles; SCSS structural tokens (`$space-*`, `$color-*`, `$border-*`,
+  `focus_ring`) via `@use 'kit-deps' as *` (aliased to `vendor/gnexus-ui-kit/src/scss`
+  in loadPaths). Typography tokens are NOT exported by kit-deps — use the
+  `--gn-font-*` CSS variables or literals.
+- **Icons**: Phosphor web font. Icon props and classes must carry the `ph` base
+  class and `ph-` prefix (`ph ph-copy`, or `ph-copy` is auto-prefixed by kit).
+- App-owned classes (`.card-grid-*`, `.card-modal-*` on CardGrid content, chat
+  domain cards, `.session-item`) are locked by tests — do not rename.
+- Surfaces intentionally NOT kit components (documented escape hatches):
+  LoginScreen (SSO redirect, GnLoginCard doesn't fit), chat domain cards,
+  MessageList, ImageLightbox.
