- **Componenti**: Shadcn UI with an operational design.

### Database Schema
The database supports managing users, guards, certifications, sites, shifts, shift assignments, notifications, customers, and service types. It also includes tables for advanced scheduling constraints such as guard constraints, site preferences, contract parameters, training courses, holidays, and absences. Service types include specialized parameters like `fixedPostHours`, `patrolPassages`, `inspectionFrequency`, and `responseTimeMinutes`.

### Core Features
- **Multi-Sede Operational Planning**: Location-first approach for shift planning, filtering resources by selected branch.
- **Service Type Classification**: Classifies services as "fisso" (fixed posts) or "mobile" (patrols, inspections) to route sites to appropriate planning modules.
- **Planning Fissi**: Weekly planning grid for fixed posts, enabling shift creation with guard availability checks.
- **Planning Mobile**: Guard-centric interface for mobile services, displaying guard availability and hours, with an interactive Leaflet map showing sites.
- **Customer Management**: Full CRUD operations for customer details and customer-centric reporting with CSV export.
- **Dashboard Operativa**: Live KPIs and real-time shift status.
- **Gestione Guardie**: Complete profiles with skill matrix, certification management, and badge numbers.
- **Gestione Siti/Commesse**: Sites are associated with service types, including schedule, contract management, and location assignment. Automatic geocoding is supported.
- **Pianificazione Turni**: 24/7 calendar, manual guard assignment, basic constraints, and shift statuses.
- **Advanced Planning**: Management of guard constraints, site preferences, contract parameters, training courses, holidays, and absences. Includes patrol route persistence and exclusivity constraints between fixed and mobile shifts.
- **Guard Planning Views**: Dedicated views for guards to see their fixed post shifts and mobile patrol routes.
- **Site Planning View**: Coordinators can view all guards assigned to a specific site over a week.

### User Roles
- **Admin**: Full access.
- **Coordinator**: Shift planning, guard assignment, operational site management, reporting.
- **Guard**: View assigned shifts, time-punching, notifications, personal profile.
- **Client**: View assigned sites, service reporting, KPIs.

### Critical Date/Timezone Handling
The system handles timezone conversions for shift times, converting Italy local time from the frontend to UTC for database storage, and back to Italy local time for display, accounting for DST.
