/* Layout: the globe sits in the middle of the screen; the question card is centred above it and the answer sheet
   centred below it, on every screen size. Radius rule: panels 20px, controls pill, inner blocks 14px.
   Globe and flat map use the street-map palette (grey-beige land, soft blue water); one hot-pink accent stands out on it. */
