/* Fictilis · veste grafica delle pagine dei casi di studio (dal 2026-10-12: quella di www.fictilis.it).
   Fondi caldi «bone», grafite, accento rame; Space Grotesk per i titoli e Instrument Sans per il testo
   (_comune/caratteri.css, stessi file del sito, stessa origine). Intestazione, sottomenu di sezione e piè
   di pagina replicano quelli del sito (components/layout/Header.tsx, SectionSubNav.tsx, Footer.tsx).
   Logo: SEMPRE il logo ufficiale — scritta scura nell'intestazione, lockup chiaro nel piè di pagina grafite.
   ⚠️ I colori dei DATI non sono di interfaccia e non seguono la palette: --spill, --air, --crit, --serious,
   --warn e --water restano quelli del motore (legende, zone, colonne dei risultati). Il rame del sito
   (#BE5E30) è quasi identico a --spill: per questo l'acqua ha il suo --water e i dati non usano --brand. */
