/* /ia-automacao — composição própria. Conceito: da pergunta à ação.
   Linguagem: estados que se transformam (pergunta → contexto → fontes → resultado → ação), trilhos que ligam nós
   exatamente pelo centro, interfaces que mostram fontes e prévias — nunca raciocínio interno.
   Ritmo: hero claro com o caminho completo → contexto (branco, explorável) → fontes (claro) → ação (escuro)
   → controle (branco) → Flow Builder (claro, explorável) → entre áreas (branco) → atendimento (claro)
   → conhecimento (branco) → infraestrutura (escuro) → Kyra × automação (branco, explorável) → pessoas → fechamento.
   Estados ocultos de motion só existem com .is-armed (aplicado pelo JS). */
