/* ============================================================
   Nebo — Design system (tema LIGHT, unico previsto: l'app e'
   light-only, nessuna dark mode introdotta).

   Fonte canonica dei token: styleguide approvato (nebo-design-
   system.html, generato durante la sessione di design). Sostituisce
   gli stili di default del template Blazor (Helvetica generico,
   blu #1b6ec2, sidebar viola/navy) con l'identita' Nebo: primary
   petrol/teal, sidebar slate, tipografia IBM Plex.

   Applicato in modo puramente visivo/di presentazione: nessuna
   logica applicativa, nessun markup di business toccato. I colori
   di stato (urgente/non-assegnato/risolto) restano semanticamente
   gli stessi, solo ricalibrati per contrasto (NFR-040,
   Services/TicketHighlightStyles.cs — classi invariate, la
   ricolorazione avviene qui sulle classi Bootstrap gia' emesse).
