## Setup

### 1. Install packages

```bash
bun add @loke/design-system @loke/icons @loke/ui
```

### 2. Configure Tailwind CSS

Create or update your app's CSS entry point. The consumer must duplicate the `@theme` block and `:root`/`.dark` variables, then add an `@source` directive pointing to the design system package so Tailwind v4 does not purge DS classes.

```css
/* src/styles.css */
@import "tailwindcss";

@plugin "tailwindcss-animate";

/* Point Tailwind at the DS package so its classes are not purged */
@source "../../../packages/design-system";  /* monorepo path -- see note below */

@custom-variant dark (&:is(.dark *));

@theme inline {

  }
  body {
    @apply bg-background text-foreground;
  }
  button {
    @apply cursor-pointer;
  }
}
```

### 3. Import the stylesheet and add TooltipProvider

Import the DS stylesheet at your app entry point and wrap your tree with `TooltipProvider`.

```tsx
// src/main.tsx (or app entry)
import "@loke/design-system/styles";
import { TooltipProvider } from "@loke/design-system/tooltip";

export default function App() {
  return (
    <TooltipProvider>
      {/* your app */}
    </TooltipProvider>
  );
}
```

## Core Patterns

### Subpath imports

Every component lives at its own subpath. There is no barrel export.

```tsx
import { Button } from "@loke/design-system/button";
import { Input } from "@loke/design-system/input";
import { Dialog, DialogContent, DialogTitle } from "@loke/design-system/dialog";
import { cn } from "@loke/design-system/cn";
import { Badge } from "@loke/design-system/badge";
import { Tooltip, TooltipContent, TooltipTrigger } from "@loke/design-system/tooltip";
```

Full list of available subpaths (from `package.json` exports):

`accordion` `alert` `alert-dialog` `avatar` `badge` `box` `button` `calendar`
`card` `checkbox` `cn` `collapsible` `columns` `command` `date-picker` `dialog`
`dropdown-menu` `form` `heading` `inline` `input` `label` `max-width-wrapper`
`page-layout` `pagination` `popover` `radio-group` `responsive` `select`
`separator` `sheet` `sidebar` `skeleton` `slot` `spinner` `stack` `switch`
`table` `tabs` `text` `textarea` `toast` `tooltip` `use-mobile`

### Stylesheet import

```ts
import "@loke/design-system/styles";
```

Import once at the app entry point, before any component imports.

### Dark mode

Dark mode is class-based. Toggle by adding/removing the `dark` class on `<html>` or `<body>`.

```ts
document.documentElement.classList.toggle("dark");
```

The Tailwind custom variant is configured as:

```css
@custom-variant dark (&:is(.dark *));
```

This means any element inside a `.dark` ancestor gets dark styles applied.

### @source directive

**Monorepo (workspace package):**

```css
@source "../../../packages/design-system";
```

**External npm dependency:**

```css
@source "../node_modules/@loke/design-system";
```

Adjust the relative path to match your app's location relative to the DS package root.

## Common Mistakes

### 1. CRITICAL: Importing from barrel path instead of subpath

```tsx
// Wrong -- no barrel export exists
import { Button } from "@loke/design-system";

// Correct
import { Button } from "@loke/design-system/button";
```

### 2. CRITICAL: Using shadcn-style import paths

```tsx
// Wrong -- this is a shadcn/ui pattern, not used here
import { Button } from "@/components/ui/button";

// Correct
import { Button } from "@loke/design-system/button";
```

### 3. CRITICAL: Missing stylesheet import

```tsx
// Wrong -- components render unstyled
import { Button } from "@loke/design-system/button";

// Correct -- import the stylesheet once at app entry
import "@loke/design-system/styles";
import { Button } from "@loke/design-system/button";
```

### 4. HIGH: Using overlay components in server components

```tsx
// Wrong -- Dialog, Popover, Tooltip, Sheet etc. use browser APIs
// app/page.tsx (React Server Component)
import { Dialog } from "@loke/design-system/dialog";
export default function Page() {
  return <Dialog>...</Dialog>; // runtime error
}
```

```tsx
// Correct -- add "use client" boundary
// app/components/my-dialog.tsx
"use client";

import { Dialog, DialogContent, DialogTrigger } from "@loke/design-system/dialog";

export function MyDialog() {
  return (
    <Dialog>
      <DialogTrigger>Open</DialogTrigger>
      <DialogContent>Content</DialogContent>
    </Dialog>
  );
}
```

```tsx
// app/page.tsx
import { MyDialog } from "./components/my-dialog";

export default function Page() {
  return <MyDialog />;
}
```

### 5. HIGH: Importing primitives from @loke/design-system instead of @loke/ui

```tsx
// Wrong -- arrow, focus-scope, popper, portal, presence, roving-focus
// are internal primitives not exported from @loke/design-system
import { Presence } from "@loke/design-system/presence";
import { FocusScope } from "@loke/design-system/focus-scope";
import { Portal } from "@loke/design-system/portal";

// Correct -- primitives live in @loke/ui
import { Presence } from "@loke/ui/presence";
import { FocusScope } from "@loke/ui/focus-scope";
import { Portal } from "@loke/ui/portal";
```

> Fixed in v2.0.0-rc.5. Agents trained on older code may still generate this pattern.

### 6. HIGH: Hallucinating @radix-ui/react-* imports

```tsx
// Wrong -- @radix-ui packages are internal deps, not consumer-facing
import * as DialogPrimitive from "@radix-ui/react-dialog";
import * as PopoverPrimitive from "@radix-ui/react-popover";

// Correct -- use the DS exports directly
import { Dialog, DialogContent, DialogTrigger } from "@loke/design-system/dialog";
import { Popover, PopoverContent, PopoverTrigger } from "@loke/design-system/popover";
```

### 7. HIGH: Missing @source directive in consumer Tailwind CSS

```css
/* Wrong -- DS utility classes get purged at build time */
@import "tailwindcss";

@theme inline {
  /* ... */
}
```

```css
/* Correct -- monorepo */
@import "tailwindcss";
@source "../../../packages/design-system";

@theme inline {
  /* ... */
}
```

```css
/* Correct -- external npm */
@import "tailwindcss";
@source "../node_modules/@loke/design-system";

@theme inline {
  /* ... */
}
```
