 *
 * Loaded by:
 *   - views/not-logged-in/new_frontpage.php  (the marketing landing page)
 *   - components/not-logged-in/marketing_header.php  (header partial used by
 *     every public view that opts into the new layout)
 *
 * When updating colours or layout primitives, change them here and they
 * propagate to every page that includes the marketing header.
