/**
 * Site Mechanic - UI State Patterns
 * Loading, Empty, Error, Success states for consistent UX
 *
 * Usage:
 * - .ui-loading: Show spinner with optional message
 * - .ui-empty: Empty state with icon and call-to-action
 * - .ui-error: Error state with retry option
 * - .ui-success: Success confirmation with optional next action
