Spacedrive's UI is built on a set of reusable primitives from `@sd/ui`. These components provide consistent styling and behavior across the application.

## Design Principles

### Composition Over Configuration

Primitives are simple, composable building blocks rather than complex configured components.

```tsx
// Complex configuration
<DataTable
  columns={...}
  data={...}
  filters={...}
  pagination={...}
/>

// Composable primitives
<div className="overflow-hidden rounded-lg border border-app-line">
  <table className="w-full">
    <thead className="bg-app-box">
      <tr>
        <th className="px-4 py-3 text-xs text-ink-dull">Name</th>
      </tr>
    </thead>
    <tbody className="divide-y divide-app-line">
      {data.map(item => (
        <tr className="bg-app-input/30">
          <td className="px-4 py-3 text-ink">{item.name}</td>
        </tr>
      ))}
    </tbody>
  </table>
</div>
```

### Semantic Color Usage

All primitives use semantic color tokens, never raw Tailwind colors.

```tsx
// Raw colors
<div className="bg-gray-800 text-gray-200">

// Semantic colors
<div className="bg-app-box text-ink">
```

### Consistent Patterns

Common patterns are standardized across primitives:

**Card Pattern:**
```tsx
<div className="relative overflow-hidden rounded-2xl bg-sidebar/90 backdrop-blur-xl shadow-2xl">
  <div className="absolute top-0 h-px w-full bg-gradient-to-r from-transparent via-[#2D2D37]/60 to-transparent" />
  <div className="absolute bottom-0 h-px w-full bg-gradient-to-r from-transparent via-[#2D2D37]/60 to-transparent" />

  <div className="noise noise-faded noise-sm p-6">
    {/* Content */}
  </div>
</div>
```

**List Item Pattern:**
```tsx
<div className="rounded-lg border border-app-line bg-app-input/30 p-4 hover:bg-app-input/40">
  {/* Content */}
</div>
```

**Table Pattern:**
```tsx
<div className="overflow-hidden rounded-lg border border-app-line">
  <table className="w-full">
    <thead className="bg-app-box">
      <tr>
        <th className="px-4 py-3 text-xs font-medium text-gray-400">
          Column
        </th>
      </tr>
    </thead>
    <tbody className="divide-y divide-app-line">
      <tr className="bg-app-input/30 hover:bg-app-input/50">
        <td className="px-4 py-3 text-ink">Data</td>
      </tr>
    </tbody>
  </table>
</div>
```

## Core Primitives

### Button

Versatile button component with multiple variants and sizes.

```tsx
import { Button } from '@sd/ui';

<Button variant="accent" size="md">
  Primary Action
</Button>

<Button variant="gray" size="sm">
  Secondary Action
</Button>

<Button variant="default" size="lg">
  Tertiary Action
</Button>
```

**Variants:**
- `default` - Transparent with border, hover/active states
- `gray` - App button background with hover/focus states
- `accent` - Accent blue background with white text
- `subtle` - Transparent border, subtle hover
- `outline` - Sidebar line border style
- `dotted` - Dashed border for add/create actions
- `colored` - Custom colored backgrounds (pass bg color class)
- `bare` - No styling whatsoever

**Sizes:**
- `xs` - Extra small (px-1.5 py-0.5, text-xs)
- `sm` - Small (px-2 py-0.5, text-sm) - default
- `md` - Medium (px-2.5 py-1.5, text-sm)
- `lg` - Large (px-3 py-1.5, text-md)
- `icon` - Square icon button (!p-1)

**Best Practice:** Wrap icons and text in flex containers to prevent stacking:

```tsx
<Button className="flex items-center gap-2">
  <Icon size={16} weight="fill" />
  <span>Label</span>
</Button>
```

### Input

Form input with semantic styling and size variants.

```tsx
import { Input, Label } from '@sd/ui';

<div>
  <Label>Username</Label>
  <Input
    placeholder="Enter username"
    size="lg"
    error={hasError}
  />
</div>
```

**Variants:**
- `default` - Standard input with border and background
- `transparent` - Transparent background, no border on focus

**Sizes:**
- `xs` - 25px height
- `sm` - 30px height (default)
- `md` - 36px height
- `lg` - 42px height
- `xl` - 48px height

**Props:**
- `error` - Shows error state (red border/ring)
- `icon` - Icon component or React node
- `iconPosition` - `'left'` | `'right'` (default: `'left'`)
- `right` - React node to display on the right side
- `inputElementClassName` - Additional classes for the input element itself

**Additional Components:**
- `SearchInput` - Input with MagnifyingGlass icon pre-configured
- `PasswordInput` - Input with eye icon toggle for show/hide password
- `TextArea` - Multi-line text input with same styling system
- `Label` - Semantic label component with slug prop for htmlFor

### Form Components

React Hook Form integration with automatic validation display.

```tsx
import { Form, InputField, z } from '@sd/ui/src/forms';
import { useForm } from 'react-hook-form';
import { zodResolver } from '@hookform/resolvers/zod';

const schema = z.object({
  username: z.string().min(3),
  email: z.string().email(),
});

function MyForm() {
  const form = useForm({
    resolver: zodResolver(schema),
  });

  return (
    <Form form={form} onSubmit={form.handleSubmit(onSubmit)}>
      <InputField
        name="username"
        label="Username"
        placeholder="Enter username"
      />
      <InputField
        name="email"
        label="Email"
        type="email"
      />
      <Button type="submit">Submit</Button>
    </Form>
  );
}
```

### Switch

Toggle switch for boolean settings.

```tsx
import { Switch } from '@sd/ui';

const [enabled, setEnabled] = useState(false);

<div className="flex items-center justify-between">
  <div>
    <div className="text-sm text-ink">Enable Feature</div>
    <div className="text-xs text-ink-dull">Description</div>
  </div>
  <Switch checked={enabled} onCheckedChange={setEnabled} />
</div>
```

### ShinyToggle

Animated toggle component for switching between multiple options with a smooth glowing indicator.

```tsx
import { ShinyToggle } from '@sd/ui';

const [view, setView] = useState<'grid' | 'list'>('grid');

<ShinyToggle
  value={view}
  onChange={setView}
  options={[
    { value: 'grid', label: 'Grid', count: 42 },
    { value: 'list', label: 'List', count: 42 },
  ]}
/>
```

**Features:**
- Smooth animated indicator using Framer Motion
- Gradient background with glow effect
- Optional count badges
- Type-safe with generics
- Fully accessible

**Props:**
- `value` - Current selected value (generic type T)
- `onChange` - Callback when selection changes
- `options` - Array of `{ value: T, label: ReactNode, count?: number }`
- `className` - Additional classes for the container

### DropdownMenu

Context menu and dropdown with Radix UI.

```tsx
import { DropdownMenu } from '@sd/ui';

<DropdownMenu.Root
  trigger={
    <button>Open Menu</button>
  }
>
  <DropdownMenu.Item
    label="Action"
    icon={IconComponent}
    onClick={handleClick}
  />
  <DropdownMenu.Separator />
  <DropdownMenu.Item
    label="Delete"
    icon={TrashIcon}
    variant="danger"
  />
</DropdownMenu.Root>
```

## Glassmorphism Effect

Spacedrive's signature glassmorphism effect combines backdrop blur, transparency, and gradient borders.

```tsx
<div className="relative overflow-hidden rounded-2xl bg-sidebar/90 backdrop-blur-xl shadow-2xl">
  {/* Top gradient border */}
  <div className="absolute top-0 h-px w-full bg-gradient-to-r from-transparent via-[#2D2D37]/60 to-transparent" />

  {/* Bottom gradient border */}
  <div className="absolute bottom-0 h-px w-full bg-gradient-to-r from-transparent via-[#2D2D37]/60 to-transparent" />

  {/* Content with noise texture */}
  <div className="noise noise-faded noise-sm p-6">
    Content
  </div>
</div>
```

**Noise Variants:**
- `noise` - Base noise texture
- `noise-faded` - Faded intensity
- `noise-sm` - Small grain size

## Progress Bars

Consistent progress bar pattern for resource usage.

```tsx
<div>
  <div className="mb-2 flex items-center justify-between text-xs">
    <span className="text-ink-dull">Storage</span>
    <span className="text-ink">45/100 GB</span>
  </div>
  <div className="h-2 overflow-hidden rounded-full bg-app-box">
    <div
      className="h-full bg-accent"
      style={{ width: '45%' }}
    />
  </div>
</div>
```

**Color by type:**
- Storage: `bg-accent` (blue)
- AI/Compute: `bg-purple-500`
- Bandwidth: `bg-green-500`
- Progress: `bg-blue-500`
- Success: `bg-green-400`

## Status Badges

Standard status badge pattern.

```tsx
const STATUS_CONFIG = {
  running: { color: 'text-green-400', bg: 'bg-green-500/20' },
  stopped: { color: 'text-gray-400', bg: 'bg-gray-500/20' },
  error: { color: 'text-red-400', bg: 'bg-red-500/20' },
};

<div className={`flex items-center gap-1.5 rounded-full px-2.5 py-1 ${STATUS_CONFIG.running.bg}`}>
  <div className="h-1.5 w-1.5 rounded-full bg-green-400" />
  <span className={`text-xs font-medium ${STATUS_CONFIG.running.color}`}>
    Running
  </span>
</div>
```

## Empty States

Pattern for when lists/grids are empty.

```tsx
<div className="rounded-lg border border-dashed border-app-line bg-app-box/50 p-12 text-center">
  <Icon size={48} weight="fill" className="mx-auto mb-3 text-ink-dull" />
  <h3 className="mb-1 text-lg font-semibold text-white">
    No items yet
  </h3>
  <p className="mb-4 text-sm text-ink-dull">
    Description of what would appear here
  </p>
  <Button variant="accent" size="lg">
    Create First Item
  </Button>
</div>
```

## Gradients

### Background Gradients

```tsx
<div className="bg-gradient-to-br from-accent to-blue-600">
  Icon background
</div>

<div className="bg-gradient-to-b from-white to-gray-400 bg-clip-text text-transparent">
  Gradient text
</div>
```

### Border Gradients

```tsx
<div className="h-px w-full bg-gradient-to-r from-transparent via-[#2D2D37]/60 to-transparent" />
```

## Typography Scale

Consistent text sizing across the app.

```tsx
<h1 className="text-3xl font-bold text-ink">
  Page Title
</h1>

<h2 className="text-xl font-semibold text-white">
  Section Title
</h2>

<p className="text-sm text-ink-dull">
  Description text
</p>

<span className="text-xs text-ink-faint">
  Helper text
</span>
```

**Scale:**
- `text-xs` (12px) - Helper text, labels
- `text-sm` (14px) - Body text, descriptions
- `text-base` (16px) - Default body
- `text-lg` (18px) - Subheadings
- `text-xl` (20px) - Section titles
- `text-2xl` (24px) - Card titles
- `text-3xl` (30px) - Page titles

## Icons

Use Phosphor Icons with consistent sizing and weights.

```tsx
import { Icon } from '@phosphor-icons/react';

<Icon size={16} weight="fill" />  // Buttons, small UI
<Icon size={20} weight="fill" />  // Medium UI elements
<Icon size={24} weight="fill" />  // Large icons
<Icon size={32} weight="fill" />  // Headers
<Icon size={48} weight="fill" />  // Empty states
```

**Weight Guidelines:**
- `regular` - Default, inactive states
- `fill` - Active states, buttons, emphasis
- `bold` - Strong emphasis

## Spacing Scale

Consistent spacing using Tailwind's scale.

**Common patterns:**
- Card padding: `p-6`
- Button padding: `px-3 py-1.5` (md), `px-2.5 py-1.5` (sm)
- Section spacing: `space-y-4` or `space-y-6`
- Grid gaps: `gap-4` or `gap-6`
- Icon-text gap: `gap-2` or `gap-3`

## Accessibility

### Color Contrast

All semantic colors meet WCAG AA standards:
- `text-ink` on `bg-app` - AAA
- `text-ink-dull` on `bg-app-box` - AA
- `text-ink-faint` on `bg-app-input` - AA (minimum)

### Focus States

Interactive elements include focus rings:

```tsx
<button className="
  focus:outline-none
  focus:ring-2
  focus:ring-accent
  focus:ring-offset-2
  focus:ring-offset-app-box
">
```

### Keyboard Navigation

All interactive primitives support keyboard navigation out of the box via Radix UI.
