/* Preview A, the story (views/preview/a.ts, static/js/scrolly.js): one product made from one set of requirements,
   told by scrolling. The design system of the previous A (static/css/preview-a.css, now /preview/landing/a-v2):
   Schibsted Grotesk and JetBrains Mono, a 12-column grid, a cool grey page, ink in three strengths, hairlines,
   copper for the main action only, the product colours only in the wordmarks. New here: the sticky stage of the
   story (a canvas over pre-rendered pictures, the requirements as a document, code and plots on dark screens),
   the hero picture, the ledger and the composer at the end. Radius 4 px on controls, none on panels; no shadows. */
