 * Timeline — looping milestone carousel.

 * Buildings are grayscale; the slide in focus (Splide .is-active, centred) goes to colour,
 * scales up and reveals its name + location and a dotted guide line. A year + dot row sits
 * under every building, joined by a thin line. Arrows appear on hover; touch uses drag.
