/* Bright Green Book — site.css
   Section layout, header/menu, cards, hero animation, catalog, forms.
   Built on top of modernist.css tokens — never a hard-coded hex/px here that
   the tokens already carry. Responsive strategy goes beyond the handoff's
   single breakpoint: 1400 / 1100 / 820 / 640px, so grids, the hero and the
   purchase table stay legible and touch-friendly at every size, not only
   past the final collapse. */
