/**
 * Public/marketing nav — single source of truth for the masthead on every
 * public page. Loaded automatically by nav-public.php.
 *
 * "The Periodical" redesign (2026-06-22): translucent paper bar + hairline
 * rule, body-font links, green CTA. Uses theme.css tokens with literal
 * fallbacks so it renders correctly on pages that have NOT yet loaded
 * theme.css (during the page-by-page conversion).
