/* AIClient — stile condiviso landing + pagine legali.
   Tema "Elegante e profondo": fondo inchiostro, accento oro, secondario
   verde-acqua. I valori rispecchiano src/lib/tokens.ts (stessa palette dell'app)
   così la landing e /app/ sembrano lo stesso prodotto.
   Statico, zero dipendenze, niente framework. */
