/* roadmap.css — the beginner AI roadmap. Loaded after theme.css and takes every colour, type
 * size, radius, shadow and motion value from its tokens, exactly as home.css does on the Whizply
 * home, so the two pages look like one product (dark mode included).
 *
 * LOOK: the home's. A hero on the soft wash with two drifting glows, two-tone headings (a dark
 * first sentence, then a continuation in the accent), white cards with soft shadows, sections
 * that alternate on the contrast-matched bands (violet, page wash, navy, mint), crisp accent
 * buttons with small radii.
 *
 * MOTION: the hero arrives in order; the map draws its road, pops its stops in and floats the
 * robot over your current step; blocks rise into view as you scroll; tabs slide their underline;
 * the rail slides its highlight; ticks draw themselves; a finished step bursts a few sparks.
 * Only transform and opacity move. Everything is still under prefers-reduced-motion. */
