/* Layout: bold, editorial-authority take — Gustavo's photo runs full-bleed behind the hero in
   grayscale/gold duotone (serious, not decorative), a serif display face carries the big claims
   for gravitas, and the rest of the page reads like a ledger: thin gold rules, hard contrast,
   no soft edges. Built to feel like proof, not a pitch. */
