   GOLDILLA REFRIGERATION SERVICES — bespoke static site
   Design: "el frío profesional, hecho web" — navy + ice blue + gold.
   Palette extracted from logo/poster by code (PIL), gold sampled from the
   GOLDILLA wordmark: median #f1cf63, highlight #fad76a. Navy/ice from logo:
   #05214c · #164a7f · #70a1b6 · #a2bfd4 · #bfd8d9 · #fbfbfc.
   Type: Sora (display, geometric, confident) + Inter (body).
   NOTE: all copy is real — from Goldilla's own promo graphics (tagline,
   subtitle, mission, the three service descriptions, the trust block).
   No invented services, prices or claims.
