/* INTEGRAÇÕES · CONTAINER 03 · COMO O CHANNEL MANAGER E O MOTOR FUNCIONAM (único container gráfico) — v0.84.0
   Animação 100% em CSS, ciclo de 14 s (--uos-fl-cycle) em quatro tempos:
   1 reserva sai de um canal (0–25%) · 2 chega ao mapa do uOS (25–50%) · 3 disponibilidade e tarifas voltam aos canais e vão ao motor (50–75%) · 4 o site confirma (75–100%).
   Ajuste: --uos-fl-cycle. prefers-reduced-motion: tudo parado, no estado final. Palco decorativo (aria-hidden); a lista de passos é a versão em texto.
   ≥901px: palco em linha; até 900px: palco em coluna (as linhas viram verticais). */
