   NCC MANAGER — SHARED BASE STYLES
   ═══════════════════════════════════════════════════════
   Regole CSS COMUNI tra calendario principale (index.html + app.css)
   ed event_editor.php. Estratte da mobile-enhancements.css per evitare
   asimmetrie visive tra i 2 contesti (vedi incident Eventi v1.4).

   Includere:
   - in index.html: <link rel="stylesheet" href="assets/css/shared-base.css">
     DOPO assets/css/app.css ma PRIMA di mobile-enhancements.css
   - in event_editor.php: <link rel="stylesheet" href="assets/css/shared-base.css">
     DOPO il <style> inline esistente

   Nota: regole responsive specifiche del calendario (grid mobile, sidebar
   drawer, dashboard responsive, safe area iPhone) restano in mobile-enhancements.css.
   Questo file contiene SOLO ciò che ha senso per entrambi i contesti.
