/* ============================================
   FIX: Modal Backdrop Z-Index Issue
   Problema: Bootstrap modal-backdrop copre il calendario

   ============================================ */

/* ============================================
   SOLUZIONE DEFINITIVA Z-INDEX - v3.5.0
   Basata su analisi Playwright del DOM reale

   Problema rilevato:
   - Header tema: z-index 999
   - Header search form: z-index 9999
   - Backdrop era a 10 → SOTTO header (header visibile sopra backdrop!)

   Hierarchy corretta:
   - Modale: 1055 (SOPRA tutto)
   - Backdrop: 1040 (oscura header e contenuto)
   - Header tema: 999 (SOTTO backdrop)

   Fix: Backdrop a 1040 (sopra header), modale a 1055 (sopra backdrop)
   ============================================ */

/* ============================================
