 * Christmas Festival Theme CSS - OVERLAY EFFECTS ONLY
 * Standard CSS for Hyva theme compatibility
 * Creates overlay effects WITHOUT modifying existing theme
 * All effects are positioned as overlays that don't interfere with existing design
 * NO modifications to existing theme elements - PURE OVERLAY SYSTEM
 * 
 * IMPORTANT: Effects only show when JavaScript adds the specific classes
 * This ensures admin configuration controls visibility
