/* ════════════════════════════════════════════════════════════════
   DOBRA 03 · JORNADA DOS CICLOS (.imj-) — escopo próprio.
   Tema claro do projeto: fundo gelo #e9ebef · texto #0c0e14 ·
   glass cards brancos · acentos roxos (#8b5cf6 / #7c3aed).

   Desktop (JS ativo, [data-journey-on]): a seção é pinada (~350vh)
   e a "câmera" desce pela trilha — o track sobe, a curva SVG se
   desenha e a etapa sob o centro ganha foco com leve rotateX 3D.
   Mobile: timeline vertical com linha de progresso.
   Sem JS / reduced-motion: o atributo nunca é aplicado e tudo
   fica empilhado, estático e legível (fallback).
