/* ─────────────────────────────────────────────────────────────────────────
   Liravira — landing page
   Design read: trust-first landing for foreign owners of Portuguese property.
   Calm, premium, direct. Dials: VARIANCE 6 / MOTION 4 / DENSITY 3.

   Locks (per the taste skill):
   • One accent (blue), used on the whole page. No second accent.
   • Radius: interactive = full pill; panels/cards = 16px; inputs = 10px.
   • Theme: light throughout; the final CTA band is the ONE deliberate dark moment.
   • Type: Geist (display + body), Geist Mono for numeric accents.
   • No em-dashes anywhere visible. Off-black ink, never pure black.
   Four sections: hero (split) · watch (grid) · how (process) · cta (band).
