## Configuration

The site configuration is now **modular** — split into focused files in `src/lib/config/` for easier maintenance. You can still import everything from `$lib/config` for backward compatibility.

### Config File Structure

```
src/lib/config/
├── index.ts       # Barrel export (re-exports all modules)
├── user.ts        # User profile, socials, skills
├── layout.ts      # Layout dimensions, breakpoints, fonts, navbar, scrollbar
├── theme.ts       # Colors, animations, effects, loading screen
├── content.ts     # Projects, 3D models, hackathon cards
├── terminal.ts    # Terminal settings, TUI styling, speed presets, shortcuts
└── navigation.ts  # Navigation links, site metadata, page meta
```

### Import Examples

```typescript
// Barrel import (backward compatible)
import { user, colorPalette, projects } from '$lib/config';

// Direct imports (smaller bundles, faster builds)
import { user, skills } from '$lib/config/user';
import { colorPalette, animations } from '$lib/config/theme';
import { projects, models, cards } from '$lib/config/content';
import { terminalSettings, keyboardShortcuts } from '$lib/config/terminal';
import { navigation, site, pageMeta } from '$lib/config/navigation';
```

### Config Modules

| File | Contents |
|------|----------|
| `user.ts` | `user`, `skills` |
| `layout.ts` | `layout`, `breakpoints`, `fonts`, `navbar`, `scrollbar` |
| `theme.ts` | `colorPalette`, `terminalButtons`, `loadingScreen`, `effects`, `animations` |
| `content.ts` | `projects`, `models`, `cards`, `sortedCards` + types |
| `terminal.ts` | `terminalSettings`, `tuiStyle`, `tuiText`, `pageSpeedSettings`, `pageAutoscrollSettings`, `speedPresets`, `modelViewer`, `particles`, `keyboardShortcuts` |
| `navigation.ts` | `navigation`, `site`, `pageMeta` |

### Example: Key config snippets
```typescript
// Toggle theme keys and other shortcuts
export const keyboardShortcuts = {
  skip: ['y', 'Y'],           // Skip typing animation
  toggleTheme: ['t', 'T'],    // Toggle dark/light mode
  navigateUp: ['ArrowUp', 'k'],
  navigateDown: ['ArrowDown', 'j'],
  select: ['Enter'],
};

// Terminal / typing
export const terminalSettings = {
  baseTypeSpeed: 20,
  minTypeSpeed: 5,
  maxTypeSpeed: 50,
  startDelay: 300,
  lineDelay: 100,
  showCursor: true,
  promptStyle: 'full',
  icon: '🐧',
  scrollMargin: 80,
};

// Color palette (Catppuccin Mocha by default)
export const colorPalette = {
  red: '#f38ba8',
  green: '#a6e3a1',
  yellow: '#f9e2af',
  blue: '#89b4fa',
  magenta: '#cba6f7',
  cyan: '#94e2d5',
  white: '#cdd6f4',
  gray: '#6c7086',
  error: '#f38ba8',
  success: '#a6e3a1',
};

// TUI styling example
export const tuiStyle = {
  borderRadius: 8,
  borderWidth: 2,
  width: '95%',
  bodyPadding: '1rem 1.25rem 2rem 1.25rem',
  buttonPadding: '0.5rem 0.75rem',
};
```

### How to Customize

- Edit `config/user.ts` to update your profile, socials, and skills
- Edit `config/content.ts` to add projects, models, or hackathon entries
- Edit `config/theme.ts` to change colors, animations, or loading screen
- Edit `config/terminal.ts` to adjust typing speed, TUI styling, or shortcuts
- Edit `config/layout.ts` to change dimensions, breakpoints, or navbar settings
- Edit `config/navigation.ts` to add/remove nav links or update page metadata

Changes take effect on next reload. Some values (fonts, CSS variables) may also require adjusting CSS or Tailwind config.

### Where to Look for Types & Utilities

- `src/lib/config/` — All configuration modules
- `src/lib/components/tui/types.ts` — TerminalLine types
- `src/lib/components/tui/utils.ts` — Parsing utilities and style helpers
- `src/lib/stores/theme.ts` — Theme store & `toggleMode()`
- `src/lib/index.ts` — Helper functions (barrel export)

## Speed Presets

| Preset | Effect |
|--------|--------|
| `instant` | No animation, appears immediately |
| `fast` | 3x faster than normal |
| `normal` | Default typing speed |
| `slow` | 2x slower than normal |
| `typewriter` | 3x slower, classic feel |

## Text Formatting

Use inline formatting with the `(&specs)text(&)` syntax:

### Colors

```typescript
// Basic colors
'(&red)Red text(&)'
'(&green)Green text(&)'
'(&blue)Blue text(&)'
'(&yellow)Yellow text(&)'
'(&magenta)Magenta text(&)'
'(&cyan)Cyan text(&)'
'(&orange)Orange text(&)'
'(&pink)Pink text(&)'
'(&gray)Gray text(&)'
'(&white)White text(&)'

// Semantic colors (theme-aware)
'(&primary)Primary color(&)'
'(&accent)Accent color(&)'
'(&muted)Muted text(&)'
'(&error)Error text(&)'
'(&success)Success text(&)'
'(&warning)Warning text(&)'
'(&info)Info text(&)'

// Custom hex colors
'(&#ff6b6b)Custom color(&)'
```

### Background Colors

Add `bg-` prefix to any color:

```typescript
'(&bg-red)Red background(&)'
'(&bg-blue,white)Blue bg with white text(&)'
'(&bg-surface)Surface background(&)'
'(&bg-#333333)Custom bg color(&)'
```

### Text Styles

```typescript
'(&bold)Bold text(&)'
'(&italic)Italic text(&)'
'(&dim)Dimmed text (60% opacity)(&)'
'(&underline)Underlined text(&)'
'(&strikethrough)Strikethrough text(&)'
'(&strike)Strikethrough shorthand(&)'
'(&overline)Overlined text(&)'
```

### Combining Styles

Combine multiple styles with commas:

```typescript
'(&bold,red)Bold red text(&)'
'(&italic,cyan,underline)Italic cyan underlined(&)'
'(&bg-blue,white,bold)Bold white on blue(&)'
'(&dim,strikethrough,gray)Dim gray strikethrough(&)'
```

## Line Types

### Basic Lines

```typescript
const lines: TerminalLine[] = [
  { type: 'command', content: 'ls -la' },           // With prompt prefix
  { type: 'output', content: 'File listing...' },   // Muted text
  { type: 'error', content: 'Error message' },      // Red with ✗ prefix
  { type: 'success', content: 'Success!' },         // Green with ✓ prefix
  { type: 'info', content: 'Information' },         // Primary with › prefix
  { type: 'header', content: 'Section Title' },     // Bold with # icon
  { type: 'blank', content: '' },                   // Empty line
  { type: 'divider', content: 'SECTION', id: 'section' },  // Horizontal divider with anchor ID
];
```

### Line Properties

All line types support these optional properties:

```typescript
{
  type: 'output',
  content: 'Hello world',
  id: 'my-section',      // Anchor ID for URL hash scrolling (e.g., /page#my-section)
  inline: true,          // Render inline with adjacent inline elements
  delay: 500,            // Delay before this line appears (ms)
}
```

### Button (Full-width interactive)

```typescript
{
  type: 'button',
  content: 'Click me',
  icon: 'mdi:github',           // Iconify icon
  style: 'primary',             // primary | accent | warning | error
  href: 'https://github.com',   // URL to navigate to
  external: true,               // Open in new tab (auto-detected for http/https)
  inline: true,                 // Render as compact inline button
  // OR
  action: () => doSomething(),  // Custom action
  border: false,                // Disable default border (default: true)
}
```

### Inline Elements

Multiple elements can be rendered on the same line using `inline: true`:

```typescript
// These will appear on the same line
{ type: 'output', content: 'Status:', inline: true },
{ type: 'success', content: 'Online', inline: true },
{ type: 'button', content: 'Refresh', icon: 'mdi:refresh', inline: true },

// Next line without inline breaks the group
{ type: 'blank', content: '' },
```

Supported inline types: `button`, `link`, `tooltip`, `progress`, `output`, `info`, `success`, `error`, `warning`

### Link (Inline clickable text)

```typescript
{
  type: 'link',
  content: 'Visit GitHub',
  icon: 'mdi:github',           // Optional icon
  style: 'accent',              // Styling
  href: 'https://github.com',
  external: true,               // Open in new tab (auto-detected for http/https)
}
```

### Image

```typescript
{
  type: 'image',
  content: 'Caption text',      // Optional caption
  image: '/path/to/image.png',
  imageAlt: 'Alt text',
  imageWidth: 300,              // Max width in pixels
}
```

### Card

```typescript
{
  type: 'card',
  content: 'Card body text with (&bold)formatting(&) support',
  cardTitle: 'Card Title',      // Optional header
  cardFooter: 'Footer text',    // Optional footer
  icon: 'mdi:star',             // Optional header icon
  image: '/path/to/image.png',  // Optional card image
  style: 'primary',             // Border accent color
  display: 'flex',              // flex | grid | block (controls children layout)
  children: [                   // Optional nested elements
    { type: 'button', content: 'Action', style: 'primary' }
  ],
  cardWidth: '1/2',             // Width (string fraction, decimal, or px)
  cardHeight: 300,              // Height (string fraction, decimal, or px)
  cardFloat: 'center',          // start | center | end
}
```

### Progress Bar

```typescript
{
  type: 'progress',
  content: 'Loading assets...',  // Label above bar
  progress: 75,                  // 0-100 percentage
  progressLabel: '75%',          // Custom label (defaults to percentage)
  style: 'accent',               // Bar color
}
```

### Accordion

```typescript
{
  type: 'accordion',
  content: '',
  accordionItems: [
    { title: 'Section 1', content: 'Content for section 1 with (&cyan)colors(&)' },
    { title: 'Section 2', content: 'Content for section 2' },
  ],
  accordionOpen: true,           // First item open by default
  style: 'primary',              // Accent color
}
```

### Table

```typescript
{
  type: 'table',
  content: 'Table Title',        // Optional title
  tableHeaders: ['Name', 'Role', 'Status'],
  tableRows: [
    ['Alice', 'Developer', '(&success)Active(&)'],
    ['Bob', 'Designer', '(&warning)Away(&)'],
  ],
  style: 'accent',               // Header color
}
```

### Tooltip

```typescript
{
  type: 'tooltip',
  content: 'Hover me',           // Trigger text
  tooltipText: 'This is helpful information!',
  tooltipPosition: 'top',        // top | bottom | left | right
  style: 'info',                 // Tooltip border color
}
```

### Group

Groups allow you to arrange multiple elements together with custom layout:

```typescript
{
  type: 'group',
  content: '',
  groupDirection: 'row',         // row | column (default: row)
  groupAlign: 'start',           // start | center | end
  groupGap: '1rem',              // CSS gap value
  groupGap: '1rem',              // CSS gap value
  groupExpand: true,             // Expand children to fill width (default: false)
  inline: true,                  // Render inline with other elements
  children: [
    { type: 'output', content: 'Label:', inline: true },
    { type: 'button', content: 'Action', style: 'primary', inline: true },
    { type: 'link', content: 'More info', href: '/help', inline: true }
  ]
}
```

Groups support nested groups and all element types as children. Children are rendered using the same `TuiLine` component, ensuring consistent behavior.

## TUI Components

### TerminalTUI

Main terminal component:

```svelte
<TerminalTUI 
  lines={lines}
  title="~/directory"
  interactive={true}
  speed="normal"
  autoscroll={true}
  onComplete={() => console.log('Done!')}
/>
```

Props:
- `lines` - Array of TerminalLine objects
- `title` - Terminal window title
- `interactive` - Enable keyboard navigation
- `speed` - Typing speed preset or multiplier
- `autoscroll` - Auto-scroll as content types (default: true)
- `onComplete` - Callback when typing animation finishes

### Anchor Scrolling

Add `id` to any line to create an anchor that can be linked to:

```typescript
{ type: 'divider', content: 'SKILLS', id: 'skills' },
```

Then link to it with `/portfolio#skills` - the page will scroll to that section after typing completes.

### Theme File Structure

```json
{
  "name": "Theme Name",
  "icon": "🎨",
  "dark": {
    "colors": {
      "primary": "#89b4fa",
      "secondary": "#313244",
      "accent": "#a6e3a1",
      "background": "#1e1e2e",
      "backgroundLight": "#313244",
      "text": "#cdd6f4",
      "textMuted": "#a6adc8",
      "border": "#45475a",
      "terminal": "#1e1e2e",
      "terminalPrompt": "#cba6f7",
      "terminalUser": "#a6e3a1",
      "terminalPath": "#89b4fa"
    },
    "colorMap": {
      "red": "#f38ba8",
      "green": "#a6e3a1",
      "blue": "#89b4fa",
      "primary": "var(--terminal-primary)",
      "accent": "var(--terminal-accent)",
      "muted": "var(--terminal-muted)"
    }
  },
  "light": {
    "colors": { /* light mode colors */ },
    "colorMap": { /* light mode color map */ }
  }
}
```

### Adding a New Theme

1. Create a new file: `src/lib/assets/themes/mytheme.theme.json`
2. Import it in `src/lib/stores/theme.ts`:
   ```typescript
   import myTheme from '$lib/assets/themes/mytheme.theme.json';
   ```
3. Add it to the themes object:
   ```typescript
   const themes: Record<ColorTheme, ThemeJson> = {
     arch: archTheme,
     catppuccin: catppuccinTheme,
     mytheme: myTheme as ThemeJson
   };
   ```
4. Update the `ColorTheme` type to include your theme name

### Available Themes
- **Arch Linux** (`arch`) - Classic terminal colors with Arch blue
- **Catppuccin** (`catppuccin`) - Soft, pastel Mocha/Latte colors

### Theme-Specific Colors

Beyond the basic colors, themes include:
- `teal`, `sky`, `sapphire`, `lavender` 
- `peach`, `maroon`, `mauve`
- `flamingo`, `rosewater`

```typescript
// These colors adapt to the current theme
'(&teal)Teal text(&)'
'(&lavender)Lavender text(&)'
'(&peach)Peach text(&)'
```

## Mobile Considerations

- **Viewport height**: Uses `100dvh` (dynamic viewport height) to properly handle mobile browser chrome
- **Background color**: A fallback dark background (`#1e1e2e`) is set on `html` and `body` to prevent white bars when the page content doesn't fill the viewport
- **Overflow handling**: Hidden horizontal scrollbar to prevent accidental horizontal scroll on mobile
