/* ═══ COLOR FLOW MAP (from design-spec.theme_context_map) ═══

 * GLOBAL NAV RULE:
 *   dark-top pages → nav starts transparent, white links; scrolled → solid #0B0F2A, white links
 *   light-top pages → nav starts solid #0B0F2A (force-solid), white links
 *   Logo: logo-light.svg on ALL pages (nav always dark bg in both states)
 *   body.blyr-page--dark-top → background: #0B0F2A (so transparent nav shows correct dark bg)
 *   body.blyr-page--light-top → background: #F8FAFC (content), nav force-solid dark
 *
 * index.html (dark-top):
