/*
 * Post Carousel (port sin React de la plantilla de Scrolltide, oct-2026).
 *
 * Slides and neighbours are placed entirely by `data-d` — their distance from
 * the current slide — so changing slide is one attribute per element and the
 * transitions below do the choreography.
 *
 * Las vecinas salen ~0,8 del ancho del post hacia cada lado: el contenedor
 * tiene que llevar overflow-x: clip para no abrir scroll lateral.
