/* ============================================================
   Your term: a tap-through story (Luke, 10 October 2026).
   Full-screen cards, one at a time, each with its own colours and a short
   animation: numbers count up, shoots grow, bars rise, a contour map draws.
   RULES: movement is transform and opacity (and a stroke draw) only; nothing
   flashes; no sound; every animation plays once. Under reduced motion or
   Reduce motion, the story is a plain stack of the same cards, all showing
   their final numbers, with no animation at all.
   Colours: every text and background pair here is white or near-white on a
   dark colour, checked above 4.5 to 1.
