 ## 2  Styling & theme contract
 
-### 2.1  DaisyUI token bridge
+### 2.1  CSS variables (Shadcn-native)
 
-`ui-kit/src/theme/theme.css` defines:
+All design tokens are defined in `styles/globals.css` using Shadcn conventions:
+- `:root` block for light mode (raw HSL channels, e.g. `--primary: 222 47% 31%`)
+- `.dark` block for dark mode
+- Tailwind config wraps them with `hsl()` (e.g. `primary: "hsl(var(--primary))"`)
 
-```css
-:root {
-  /* DaisyUI HSL tokens → Shadcn variables */
-  --primary:      hsl(var(--p));   /* primary */
-  --background:   hsl(var(--b1));  /* base-100 */
-  --foreground:   hsl(var(--bc));  /* base-content */
-  --border:       hsl(var(--b2));  /* base-200 */
-}
-.dark {
-  --primary:    hsl(var(--pf));
-  --background: hsl(var(--n));
-  --foreground: hsl(var(--nc));
-  --border:     hsl(var(--b3));
-}
-```
+Standard tokens: `--background`, `--foreground`, `--primary`, `--secondary`, `--accent`, `--destructive`, `--muted`, `--card`, `--popover`, `--border-color`, `--input`, `--ring`.
+
+Status tokens: `--success`, `--warning`, `--error`, `--info` (each with `-foreground` counterpart).
 
 ### 2.2  Tailwind usage rules
 
 * Use **utility classes** only inside `ui-kit`. Never emit Tailwind classes from public API.
 * Prefer semantic wrapper props over styling props.
-  Example:
-
-  ```tsx
-  <Button intent="danger" size="sm" />
-  ```
-* Use `clsx` + `tailwind-merge` helper from `ui-kit/utils/classMerge.ts` to compose class strings.
+* Use `cn()` helper (clsx + tailwind-merge) to compose class strings.
+* Use Tailwind color utilities that reference CSS vars: `bg-primary`, `text-foreground`, `border-border`, etc.
 
 ### 2.3  No inline colours
 
-* Never hard‑code colours like `bg-red-500`; always reference `bg-[hsl(var(--primary))]` or DaisyUI utility (`btn-error`).
+* Never hard-code colours like `bg-red-500`; always use semantic tokens (`bg-primary`, `bg-destructive`, `bg-success`, etc.).

 - Never override Shadcn component CSS directly; extend via wrapper props.
-- Colours/spacings via CSS vars mapped to DaisyUI tokens.

+# Add Component to UI Kit
+
+## Directory Structure
+
+Create under `packages/ui-kit/src/components/<category>/<ComponentName>/`:
+
+```
+ComponentName/
+├── index.ts              # Re-exports
+├── ComponentName.tsx     # Implementation

+```
+
+Categories: `primitives`, `form`, `feedback`, `data-display`, `layout`, `ui`, `brand`.
+
+## Implementation Checklist
+
+1. **Create component file** (`ComponentName.tsx`):
+
+   - Named export only (no default exports)
+   - Export prop interface with JSDoc
+   - Use `cn()` from `../../../lib/utils` for class merging
+   - Use Shadcn CSS variables (e.g. `bg-primary`, `text-foreground`) -- never hardcoded colors
+   - Wrap Shadcn primitives from `../../ui/` when applicable
+
+2. **Create barrel export** (`index.ts`):
+
+   ```typescript
+   export { ComponentName } from "./ComponentName";
+   export type { ComponentNameProps } from "./ComponentName";
+   ```
+
+3. **Register in parent barrel** -- add `export * from './ComponentName';` to the category's `index.ts`
+
+4. **Write tests** (`ComponentName.test.tsx`):
+
+   - Render test, prop tests, accessibility check with axe-core if applicable
+   - Use `vitest` + `@testing-library/react`
+
+5. **Verify**: Run `pnpm lint && pnpm test && pnpm build` from workspace root
+
+## Key Conventions
+
+- No `import React from 'react'` -- use `import * as React from 'react'` only if needed
+- Colors via CSS variables only: `bg-background`, `text-muted-foreground`, `border-input`
+- No DaisyUI classes -- this project uses Shadcn-native theming
+- Tailwind classes only inside ui-kit, never exposed via public API
