/* ==========================================================================
   components/orbit.css — Diagrama de sistemas conectados (hero)

   Geometria: os nós são posicionados em porcentagem via --x/--y definidos
   no HTML; o SVG usa o mesmo sistema 0–100 com preserveAspectRatio="none",
   de modo que linha e nó coincidem em qualquer proporção. vector-effect
   mantém a espessura do traço constante apesar do esticamento.

   Abaixo de 45rem o SVG é ocultado e os nós voltam ao fluxo normal —
   traço fino em tela pequena vira ruído.
