+# components/ui/ — shadcn/ui Primitives
+
+## OVERVIEW
+
+15 shadcn/ui components (new-york style, JSX). Low-level primitives — do NOT modify manually.
+
+## WHERE TO LOOK
+
+```
+accordion.jsx    button.jsx       dialog.jsx       drawer.jsx
+field.jsx        input-otp.jsx    label.jsx        progress.jsx

+
+## CONVENTIONS
+
+- **Add via CLI**: `npx shadcn@latest add <component>` — never copy-paste manually
+- **Style**: new-york, CSS variables enabled, neutral base color
+- **Icons**: lucide-react
+- **Path aliases**: `@/components/ui/*`, `@/lib/utils` (cn helper)
+- **forwardRef pattern** — all components use React.forwardRef
+- **Styling**: tailwind-merge via `cn()` in `lib/utils.js`
+
+## ANTI-PATTERNS (THIS DIRECTORY)
+
+- **Do not edit** — manual changes will be overwritten by shadcn CLI updates
+- **No custom components here** — app-specific components belong in `app/components/`
