 * Shared site chrome — nav, mobile menu, footer, reveal-on-scroll.
 * Ported from projects/op6f-prototype/OP6F.dc.html so the blog shares
 * the exact nav + footer of the marketing site. Solid brand colors route
 * through theme.json presets; alpha-blended overlays (rgba on ink/paper)
 * are kept literal since theme.json has no rgb-triplet custom properties.
 */

/*
 * theme.json's global blockGap (24px) is applied by WP as a top margin
 * between every top-level block in .wp-site-blocks (header template part,
 * main, footer template part). That margin collapses through body,
 * revealing an unstyled band above the fixed nav on every page. Our
 * sections already manage their own spacing explicitly, so this gap is
 * pure regression — kill it at the source.
