   LIMAM IMPIANTI — sistema visivo

   DIREZIONE ARTISTICA: «schema elettrico».
   Non un tema decorativo: la pagina È un circuito. Un conduttore continuo
   (.wire) la attraversa da cima a fondo e si accende mentre si scorre;
   ogni sezione è un nodo. È l'elemento firma, e nasce dal mestiere.

   PALETTE (richiesta dal cliente, call 2 [15:54] e [16:46]):
     BLU    struttura — tutte le superfici scure, la base
     GIALLO accento elettrico — marchio, CTA, numeri, stati attivi
     ROSSO  solo urgenza — pallino, pronto intervento, errori
   Il rosso non fa mai da fondo a un'area grande: resta un segnale.

   TIPOGRAFIA: Archivo variabile. Si usa l'asse di LARGHEZZA (wdth), non
   solo il peso: i titoli sono espansi, le etichette compresse. Due assi
   di contrasto invece di uno.

   MOTION: un solo motore rAF (vedi main.js). Solo transform e opacity.
   Niente backdrop-filter: uccide lo scroll e crea containing block.
