   hub-api-docs.css — Documentação de API de um Hub (superfície X-HUB)
   ─────────────────────────────────────────────────────────────────
   Serviço da X-HUB espelhado no X-DECODE: assim como o DECODE provê a
   PUBLICAÇÃO de Take, a X-HUB provê a PUBLICAÇÃO de doc de API + o
   COFRE de chave de cliente (rotação/armazenamento — Supabase Vault).

   Tema ESCURO fixo (ferramenta de dev; código lê melhor no escuro —
   coerente com "estúdio é sempre escuro"). Prefixo de escopo: .hd-*
   Acento X-HUB = laranja. Mono = Geist Mono. Display = Geist.
