/* =========================================================
   Ebook 1 — PERSUASÃO — landing page
   Design system: handoff "Ebook landing page ebook 1 — 2026"
   (tema claro off-white + acento dourado, placas de foto em
   preto pleno full-bleed).

   Regras do handoff que valem para o arquivo inteiro:
   - sem border-radius em NADA, inclusive botões;
   - sem sombra; sem gradiente decorativo (a única exceção é o
     fundo do hero, #faf8f4 -> #f4efe4);
   - dourado --gold só em fills grandes/filetes; para TEXTO sobre
     claro usa --gold-ink, que tem contraste;
   - breakpoint único em 900px.

   Fora do handoff, preservado do projeto: CTA sticky de mobile e
   o scroll reveal (o script.js depende das classes .cta,
   .cta-sticky, .reveal e de body.has-sticky-cta).
