/**
 * Deep Link Fallback Handler for Expo Router
 *
 * IMPORTANT: This file only handles deeplinks that DON'T match file-based routes.
 * For deeplinks that match file routes (like share/character/[id].tsx),
 * Expo Router will route to those files automatically.
 *
 * This handler is only used as a fallback for unmatched deeplink patterns.
 *
 * Known deeplinks handled by file routes:
 * - maerchenzauber://share/character/{id} → app/share/character/[id].tsx
 *
 * Add future deeplink handling here only if they don't match file routes.
