/* ============================================================
   instrucoes-opus5.denderson.ai
   Site standalone da aula "Ablação: reescreva seu CLAUDE.md para o Opus 5".

   Ancoragem de design (padrão dos sites que vão para a DM):
   - Paleta: agency.denderson.ai (preto quase puro + coral do Claude como
     único acento). Hex reais lidos do CSS servido daquele site.
   - Tipografia e nomes de token: estudomauricio.denderson.com, que é o
     mesmo design system do painel consultorias. Isso deixa os componentes
     da aula (infográfico, promptbox, recap, sublist) idênticos aos do
     painel sem reescrever uma linha de conteúdo.

   Regras da casa aplicadas: dark por padrão, cor sempre por token,
   zero gradiente decorativo, zero emoji, ícone só SVG inline,
   mobile-first conferido em 390px sem rolagem horizontal.
