/* ==========================================================================
   Toll-Track · Mantenimiento 360 — estilos (versión corporativa)
   Mobile first. Sin dependencias. Sin estilos en línea en el HTML (por la CSP).

   CAMBIOS DE ESTA VERSIÓN:
   - Menos espacios en blanco entre secciones (paddings y gaps más ajustados).
   - Animaciones premium: entrada del hero, reveal con variantes, spotlight en
     tarjetas, brillo en botones, tilt 3D del celular, línea de pasos que se dibuja.
   - Los hover usan la propiedad "translate" (no "transform") para no chocar con
     la animación de entrada, que sí usa "transform".
   - Tarjetas de "El problema" con imagen arriba (bloque .card-media, sección 3).

   CÓMO EDITAR COLORES:
   Todos los colores de marca están en las variables de :root (abajo).
