Scroll-linked single-page assembly

A demo built for a specific brief. Not client work: the material shown is sample data, so what is on display is the mechanism.

I built a single-page scroll narrative in which an SVG schematic assembles itself across 6 steps and 5 edges as you scroll, driven by scroll POSITION rather than scroll events so it stays correct at any speed and when a visitor lands mid-page; a ?step=N override pins any state without scrolling, and prefers-reduced-motion presents the same information as a static list rather than simply freezing.
