/* ============================================================
   GLOBAL STATE MANAGER
   Objeto singleton que centraliza toda la data en memoria.
   Se carga desde el backend con loadPersistedData() (utils.js)
   al iniciar la app, y se persiste cada 30s con persistData().

   NUNCA modificar STATE directamente desde el HTML (usar setters).
   Para cambios individuales usar save*Api() en vez de persistData()
   completo, ya que persistData() hace REPLACE TOTAL en la DB.
