/* =========================================================================
   House Of Jan x BaoBar — Landing Page di registrazione
   Redesign ispirato al layout editoriale di unvrs.com ("hyperclub"):
   tipografia display enorme in maiuscolo + UI monospace minimale,
   palette blu notte derivata dall'immagine fornita dal cliente.
   Mobile-first, nessuna dipendenza esterna oltre ai Google Fonts.

   Struttura del file:
     1. Reset & variabili (palette + type system)
     2. Tipografia
     3. Layout & utility
     4. Componenti (bottoni, badge, card, form, accordion, toast)
     5. Header
     6. Sezioni (hero, gallery, perché partecipare, giveaway, dettagli,
        form, location, faq, cta finale, footer)
     7. Animazioni on-scroll
     8. Media query responsive
