/* batterjeeplas.com v4. A dark, scroll-told story: four pinned scenes (powder becomes a tank, a statement that lights up word by word, a sideways production line, a colour dial), then the colour range, product, quality, applications, export and contact, with a guided chat. Every motion is tied to scroll and eased, never to a timer. Built from mockup v3 (2026-10-01). */
