## Key Components

**Layout**
- **Header** - Top nav, search input, user menu
- **Sidebar** - Admin side nav
- **Footer** - Version, links

**Audiobooks**
- **AudiobookCard** ✅ - Cover, title, author, narrator, duration, request button, clickable to open details modal. Shows "Requested by [username]" when someone else has requested the book, "Requested" when current user has requested it
- **AudiobookGrid** - Responsive grid (1/2/3/4 cols)
- **AudiobookDetailsModal** ✅ - Full-screen modal with comprehensive metadata (description, genres, rating, release date, narrator, request functionality). Shows requesting user's name when applicable

**Requests**
- **RequestCard** ✅ - Cover, title, author, status badge, progress bar, timestamps, action buttons (cancel, manual search, interactive search)
- **StatusBadge** - Color-coded status (pending=yellow, searching=blue, downloading=purple, downloaded=green, processing=orange, available=green, completed=green, failed=red, warn=orange, cancelled=gray). Shows "Initializing..." when downloading with 0% progress (fetching torrent info), "Downloading" when progress > 0%
- **ProgressBar** - Animated fill with percentage
- **InteractiveTorrentSearchModal** ✅ - Responsive table of ranked torrent results, uses ConfirmModal for downloads, hides columns on smaller screens (size on mobile, seeds on tablet, indexer on desktop)
- Active indicator: "Setting up..." with spinner when progress = 0%, "Active" with pulsing dot when progress > 0%

**Forms**
- **SearchBar** - Debounced input with suggestions
- **Button** - Variants (primary/secondary/outline/ghost/danger), sizes (sm/md/lg), loading state
- **Input** - Label, error display, validation, icons
- **Select** - Custom styling, search/filter
- **Modal** ✅ - Dialog overlay with backdrop, sizes (sm/md/lg/xl/full), ESC to close, body scroll lock
- **ConfirmModal** ✅ - Confirmation dialog with customizable title, message, buttons, loading state, and variant (primary/danger)
- **Pagination** ✅ - Traditional page navigation with prev/next buttons, smart ellipsis (shows 1...4 5 6...10)
- **StickyPagination** ✅ - Minimal floating pill at bottom center with prev/next arrows, quick jump input, section label. Shows/hides based on section visibility (IntersectionObserver). Rounded-full design, backdrop blur, subtle shadow, auto-scroll on page change

**Auth**
- **ProtectedRoute** ✅ - Auth check, loading state, redirects, admin role support
- **LoginPage** ✅ - Full-screen design, floating covers, Plex OAuth popup

**Admin**
- **MetricCard** - Icon, label, value, trend
- **DataTable** - Sorting, filtering, pagination
- **Chart** - Line/bar/pie

## Custom Hooks

- **useAuth** - `{user, login, logout, isLoading}`
- **useAudiobooks** - `{audiobooks, isLoading, error, totalPages, hasMore}`
- **useAudiobookDetails** ✅ - `{audiobook, isLoading, error}` - Fetches individual audiobook by ASIN
- **useRequest** - `{createRequest, cancelRequest, isLoading}`

## Styling

**Tailwind Patterns:**
- Container: `container mx-auto px-4 py-8 max-w-7xl`
- Card: `bg-white dark:bg-gray-800 rounded-lg shadow-md p-6`
- Button: `bg-blue-600 hover:bg-blue-700 text-white px-4 py-2 rounded-md`
- Grid: `grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 xl:grid-cols-4 gap-6`

**Dark Mode:** Use `dark:` variant
