## What Makes djust-theming Different?

### Design Systems Beyond Colors

Most theming libraries only change colors. djust-theming provides **complete design systems** that control:

- **Typography** - Font families, sizes, weights, and line heights
- **Spacing** - Consistent spacing scales (tight, normal, loose)
- **Border Radius** - Sharp, rounded, or pill-shaped components
- **Shadows** - Flat, subtle, material, or elevated depth systems
- **Animations** - Motion behaviors (instant, snappy, smooth, bouncy)
- **Component Styles** - Button, card, and input variants

### Mix & Match Any Design System with Any Color

**11 Design Systems:**
- **Material** - Google's Material Design with elevation-based hierarchy
- **iOS** - Apple's design language with fluid animations
- **Fluent** - Microsoft's Fluent Design System with depth and motion
- **Minimalist** - Pure, distraction-free design with maximum content focus
- **Playful** - Fun, energetic design with bouncy animations
- **Corporate** - Professional, clean design for business applications
- **Retro** - Classic web aesthetic with pixel-perfect design
- **Elegant** - Premium design with serif fonts and generous spacing
- **Neo-Brutalist** - Bold, dramatic design with sharp edges and high contrast
- **Organic** - Soft, rounded design inspired by natural forms
- **Dense** - Compact, information-dense design for data-heavy interfaces

**19 Color Presets:**
Default, Shadcn, Blue, Green, Purple, Orange, Rose, Cyberpunk, Forest, Amber, Slate, Nebula, Natural 20, Catppuccin Mocha, Rosé Pine, Tokyo Night, Nord, Synthwave '84, Outrun

MY_THEME = ThemePreset(
    name="custom",
    display_name="Custom",
    description="My custom theme",
    light=ThemeTokens(
        background=ColorScale(0, 0, 100),
        foreground=ColorScale(240, 10, 4),
        primary=ColorScale(200, 80, 50),
        primary_foreground=ColorScale(0, 0, 98),
        # ... all other tokens
    ),
    dark=ThemeTokens(
        # ... dark mode tokens
    ),
)

# Register it
THEME_PRESETS["custom"] = MY_THEME
```

## CSS Design System

The included `base.css` provides a complete design system:

- **Layout**: `.app-layout`, `.navbar`, `.sidebar`, `.content-pane`, `.container`
- **Components**: `.card`, `.btn`, `.badge`, `.alert`, `.modal`, `.toast`, `.empty-state`, `.stat-card`
- **Forms**: `.form-input`, `.form-select`, `.form-group`, `.form-label`, `.search-input`
- **Tables**: `.table`, `.table-hover`, `.table-responsive`
- **Utilities**: spacing (`.mt-4`, `.p-3`), flex (`.flex`, `.items-center`), text (`.text-sm`, `.font-bold`), colors (`.text-muted`, `.bg-muted`)
- **Animations**: fade, slide, shimmer skeleton, loading dots, toast transitions

All components use CSS custom properties from the theme, so they automatically adapt to any preset and light/dark mode.

## djust LiveView Integration

**NEW in v0.2.0:** Reactive theme switching without page reload! 🎉

```python
from djust import LiveView
from djust_theming import ThemeMixin

class DashboardView(ThemeMixin, LiveView):
    template_name = "dashboard.html"

    def mount(self, request, **kwargs):
        super().mount(request, **kwargs)
        # Theme context is automatically available:
        # self.theme_head, self.theme_switcher,
        # self.theme_preset, self.theme_mode
```

**In your template:**

```html
<!DOCTYPE html>
<html>
<head>
    {{ theme_head }}  <!-- Injects CSS + JS automatically -->
    <link href="{% static 'djust_theming/css/base.css' %}" rel="stylesheet">
</head>
<body>
    <!-- Theme switcher with reactive controls (uses dj-click/dj-change) -->
    {{ theme_switcher }}

    <!-- Your content here -->
</body>
</html>
```

**Features:**
- ✅ Theme variables injected into LiveView context via ThemeMixin
- ✅ Reactive theme mode switching (light/dark/system) without page reload
- ✅ Reactive preset switching with CSS hot-swapping (no reload needed!)
- ✅ Server-side state sync via WebSocket (`push_event`)
- ✅ Works with djust v0.3+ (djust-experimental compatible)

**How it works:**
1. User clicks theme switcher → sends `dj-click` event to server
2. Server updates theme state and pushes CSS update via `push_event('theme_update', {...})`
3. Client receives WebSocket event and updates CSS + DOM instantly (no page reload!)

This provides a **Phoenix LiveView-style reactive theming** experience.

## Tailwind CSS Integration

**NEW in v0.3.0:** First-class Tailwind CSS support! 🎨

djust-theming now generates Tailwind configs that map to your theme's CSS variables, allowing you to use theme colors directly in Tailwind classes and `@apply` directives.

### Quick Start

```bash
# Generate tailwind.config.js for your chosen preset
python manage.py djust_theme tailwind-config --preset blue --output tailwind.config.js

# Or use the default preset
python manage.py djust_theme tailwind-config
```

### Using Theme Colors in Tailwind

Once configured, use theme colors in your templates:

```html
<!-- Use theme colors in Tailwind classes -->
<button class="bg-primary text-primary-foreground hover:bg-primary/90 px-4 py-2 rounded-md">
  Primary Button
</button>

<div class="bg-card text-card-foreground border border-border rounded-lg p-6">
  Card content
</div>

<input class="bg-background border-input focus:ring-ring focus:ring-2 rounded-md px-3 py-2" />
```

### Using @apply with Theme Colors

Generate CSS examples:

```bash
python manage.py djust_theme generate-examples --output theme-components.css
```

Then use `@apply` in your CSS:

```css
.btn-primary {
  @apply bg-primary text-primary-foreground px-4 py-2 rounded-md;
  @apply hover:opacity-90 transition-opacity;
}

.card {
  @apply bg-card text-card-foreground rounded-lg border border-border;
  @apply shadow-sm p-6;
}
```

### CLI Commands

```bash
# Generate Tailwind config
python manage.py djust_theme tailwind-config [--preset PRESET] [--output FILE]

# Export colors in JSON/Python format
python manage.py djust_theme export-colors --preset blue --format json

# List available presets
python manage.py djust_theme list-presets

# Generate @apply examples
python manage.py djust_theme generate-examples --output theme.css
```

### Python API

```python
from djust_theming.tailwind import (
    generate_tailwind_config,
    export_preset_as_tailwind_colors,
    generate_tailwind_apply_examples,
)

# Generate config programmatically
config = generate_tailwind_config(preset_name='blue', extend_colors=True)
with open('tailwind.config.js', 'w') as f:
    f.write(config)

# Export colors as Python dict
colors = export_preset_as_tailwind_colors('blue')
print(colors['light-primary'])  # 'hsl(221, 83%, 53%)'
```

### Available Theme Colors in Tailwind

All theme colors are available as Tailwind utilities:

- `bg-primary`, `text-primary`, `border-primary`, etc.
- `bg-secondary`, `text-secondary`, etc.
- `bg-accent`, `bg-muted`, `bg-destructive`
- `bg-success`, `bg-warning` (extensions)
- `bg-card`, `bg-popover`, `bg-background`
- `border-border`, `border-input`
- `ring-ring` (for focus states)

All colors support opacity modifiers: `bg-primary/50`, `text-accent/80`, etc.

## shadcn/ui Compatibility

**NEW in v0.4.0:** Import and export themes in shadcn/ui format! 🔄

djust-theming is now fully compatible with shadcn/ui themes. Import themes from themes.shadcn.com or export your djust presets to share with the shadcn community.

### Import shadcn Theme

```bash
# Import a shadcn theme JSON file
python manage.py djust_theme shadcn-import my-theme.json

# Import and register it in THEME_PRESETS
python manage.py djust_theme shadcn-import my-theme.json --register
```

### Export to shadcn Format

```bash
# Export a djust preset to shadcn JSON format
python manage.py djust_theme shadcn-export --preset blue --output blue-theme.json
```

This JSON file can be:
- Uploaded to themes.shadcn.com
- Imported into other shadcn/ui projects
- Shared with the shadcn community

### Python API

```python
from djust_theming.shadcn import (
    import_shadcn_theme_from_file,
    export_to_shadcn_format,
    export_shadcn_theme_to_file,
)

# Import a shadcn theme
preset = import_shadcn_theme_from_file('custom-theme.json')
from djust_theming.presets import THEME_PRESETS
THEME_PRESETS[preset.name] = preset

# Export to shadcn format
theme_json = export_to_shadcn_format('blue')
print(theme_json['cssVars']['light']['primary'])  # '221.2 83.2% 53.3%'

# Save to file
export_shadcn_theme_to_file('blue', 'blue-theme.json')
```

### Format Compatibility

djust-theming uses the same HSL-based CSS variable system as shadcn/ui, ensuring 100% compatibility:

- ✅ All shadcn color tokens supported
- ✅ Light and dark mode variants
- ✅ Border radius configuration
- ✅ Extension tokens (success, warning) preserved
- ✅ Round-trip import/export without data loss

This means you can:
1. Find a theme you like on themes.shadcn.com
