/* DagWorld marketing site, shared styles.
 *
 * Tokens are lifted verbatim from the app's DagColors green-light and
 * green-dark sets, so the site and the product are literally the same palette
 * rather than a hand-matched approximation. If a value changes in
 * app/lib/core/ui/theme/dag_colors.dart, change it here too.
 *
 * Type follows the app's rule exactly and it is semantic, not decorative:
 *   Schibsted Grotesk  all chrome, headings, navigation, buttons
 *   Literata (serif)   quote text ONLY
 * The serif is what stops a quote reading like a UI label. Never swap them.
 *
 * The aurora is the brand's one signature gesture, and the app permits at most
 * one per screen on a low-text surface. This page spends it on the hero and
 * nowhere else.
