/* =========================================================
   Guia gratuito · Dr. Valter Filho — página de entrega do ebook (versão Plus)
   Linguagem: Design System Dr. Valter Filho (Growth Lab), a mesma do ebook.
   Direção: atlético · preciso · sóbrio. Planos alternados do DS
   (bruma → névoa → preto), rótulos numerados "■ 01 · TEMA", dourado só
   em acento e no botão (a única ação da página).
   Movimento: a tarja se desenha, o guia abre em leque, as seções entram
   ao rolar, os números contam. Tudo some com prefers-reduced-motion.
   Tipografia: Dignus / SF Pro Text quando instaladas; Saira / Inter
   (Google Fonts, carregadas no <head>) como equivalentes abertos.
