/* DEALEXUS marketing site — shared stylesheet (M202).
 *
 * One file for every marketing page that carries the redesign: the homepage,
 * how-it-works, products, pricing, insights (the blog index and every
 * article page, M203) and investors. The * pages are static HTML with no build step (CLAUDE.md §4), so the design's
 * tokens, components and motion live here once rather than in six inline
 * <style> blocks that would drift apart the way the old pages did.
 *
 * Three rules the file is held to:
 *   1. COLOUR IS A TOKEN. Every colour is a custom property with a light and a
 *      dark value. The theme follows the operating system until the visitor
 *      presses the toggle, which writes data-theme on <html>.
 *   2. MOTION IS OPTIONAL. Every animation collapses under
 *      prefers-reduced-motion, by DURATION rather than `animation: none`, so an
 *      entrance animation lands on its final frame instead of its first.
 *   3. NOTHING IS HIDDEN UNTIL A SCRIPT RUNS. Scroll reveals use scroll-driven
 *      animation where the browser has it and are plain static content where it
 *      does not; there is no `opacity: 0` waiting on an observer.
