   BLOG CABRAL — CAMADA DE MOVIMENTO "OURO VIVO"
   Irma do repo/motion.css do site principal: mesmo vocabulario de
   entrada, mesma curva, mesmo ouro. O nucleo (secoes 1 a 4) e
   deliberadamente identico nos dois arquivos — sao dois deploys
   separados, sem build compartilhado, entao a copia e o preco.
   Ao mexer no nucleo, mexa nos dois.

   Tudo o que esconde conteudo vive sob html.cm, ligado pelo
   motion.js. Sem JS ou com prefers-reduced-motion, o blog aparece
   inteiro na primeira pintura.
