/*
  Supercar Luxury Auto Broker — direzione: "digital luxury showroom" editoriale.
  Perché è diversa dalle demo precedenti (vedi DESIGN_FINGERPRINTS.md, confronto con
  Bar da Ced di Prandato Gianluca, 21/8/2026 — la più recente registrata):

  1. Geometria entrate: qui un "wipe" tecnico via clip-path legato allo scroll sull'hero
     + reveal lineare fade/slide unico per il resto — NON la cascata dal basso di Bar da Ced.
  2. Ritmo pagina: qui grafite scuro dominante e costante, con silenzi tipografici ampi —
     NON l'alternanza chiaro/scuro (crema↔oliva↔corallo) di Bar da Ced.
  3. Modello spaziale: qui piatto ed editoriale, a griglia (rivista automotive) —
     NON gli strati organici con blob sovrapposti di Bar da Ced.
  4. Tipo interazione: qui scroll-linked clip-path + count-up numerico reale sulle
     schede vettura — un signature move nuovo, mai usato prima in questo progetto.
  5. Materiale visivo: qui silhouette auto a linea tecnica (SVG) + dati come specifiche
     editoriali (maiuscolo piccolo, letter-spacing ampio) — NON blob/icone disegnate a mano.
  6. Easing: qui lineare/ease-out tecnico, mai overshoot — deliberatamente opposto
     a --ease-bounce di Bar da Ced (vedi design-direction.md del brief).
  7. Densità: qui più bassa e controllata (un solo reveal per elemento, niente parallax
     multiplo) contro la densità medio-alta e ritmata di Bar da Ced.

  Palette scelta perché nessun colore di brand ufficiale è reperibile per questa attività
  (nessun sito/social confermato): grafite/nero quasi puro + bianco caldo + ottone/bronzo,
  che richiama i dettagli cromati delle vetture premium in inventario senza il cliché
  "oro finto luxury". Font: nessun font esterno caricato (progetto zero-dipendenze, niente
  richieste di rete) — coppia editoriale ottenuta con stack di sistema (serif per i titoli,
  sans-serif tecnico per corpo/dati, con font-variant-numeric: tabular-nums sulle cifre).
