/* =========================================================================
   enautomation — sistema visivo
   =========================================================================

   Direzione: quadro strumenti, non pannello di amministrazione.
   Il prodotto sorveglia processi autonomi che spendono una quota finita, e
   l'interfaccia deve somigliare a ciò che sorveglia: superfici da strumento,
   linee sottili da disegno tecnico, numeri che si leggono a colpo d'occhio.

   Tre scelte deliberate, tutte derivate dal dominio:

   1. Il monospace è il carattere DISPLAY, non solo quello del codice. Qui
      quasi ogni valore che conta è un valore macchina — id di run, branch,
      percentuali, costi, durate, esiti. Comporli in un proporzionale è ciò
      che fa somigliare un pannello operativo a un gestionale qualunque.

   2. Il blu inchiostro al posto del nero neutro, con le linee color blueprint.
      È la tavolozza del disegno tecnico, non quella del "tema scuro".

   3. L'ambra è il colore dell'attività, non un accento decorativo: nei
      sistemi di controllo reali ambra significa "in corso, tienilo d'occhio"
      e il rosso resta al guasto. Le fasce della quota seguono la stessa
      convenzione, quindi il colore porta informazione invece di gusto.

   L'elemento firma è l'indicatore di autonomia residua (`.gauge`): una scala
   con tacche, non una barra di avanzamento, perché quello che mostra non è un
   progresso ma un serbatoio che si svuota.
