// Local Ads Fallback Provider Module
// This module provides local image fallbacks for ads
// 
// To enable clickable banners, set URLs in LOCAL_BANNER_LINKS:
// - Set to a URL string to make the banner clickable
// - Set to null to disable click functionality
// - Example: 0: 'https://example.com', 1: null, 2: 'https://another-site.com'
