/* main.css — design system v2.
   Same warm invitation palette (cream, sage, forest, terracotta), rebuilt
   with a product-site discipline: one frosted sticky header, the invitation
   artwork as the hero, wide card grids over narrow prose columns, restrained
   motion, and a consistent spacing scale. Still zero JavaScript. */
