   Stepper: 4 fases (Situación → Preguntas → Diagnóstico → Contacto) con
   footer persistente (atrás | "Paso N de 4" + barra | continuar) y slides
   direccionales entre pasos — selección → Continuar en todos los niveles.
   Superficie: panel de VIDRIO AHUMADO sobre el bosque (glass solo en
   oscuro ✓ brandbook) — texto platinum/linen, kickers chartreuse, acción
   green+ink. Coreografía de apertura: scrim 0-500ms → ramas 0-2100ms →
   viñeta ~1150ms (≈70% cobertura) → panel 1350-2050ms. Cierre: panel fuera
   → ramas se retraen (puntas primero ~760ms) → scrim 560-880ms.
   Solo se anima opacity/transform/dashoffset — los blur son constantes. */
