/* 57 · Servicios: abanico horizontal.
   Base (sin JS): tarjetas 4:5 en rejilla con el texto debajo; todo visible.
   Con JS en móvil (< 900 px): fila de tarjetas con scroll horizontal y scroll-snap; el texto aparece bajo la activa.
   Con JS en escritorio (>= 900 px): seis columnas verticales a toda la anchura (70 vh) dentro de una pista de 250 vh con la fila
   sticky; la activa crece (flex-grow 3,2), pasa a color y respira; se activa por hover y por scroll (servicios.js).
   La imagen no cambia de tamaño al abrirse la columna: su caja es fija (40 % del ancho) y centrada, y la columna la recorta. */
