/**
 * LLCBeacon header/footer/navigation — Phase 1D.
 *
 * Recreates src/components/site/SiteHeader.tsx, SiteFooter.tsx,
 * SiteSearch.tsx, StickyMobileCTA.tsx. Uses the exact 1024px breakpoint
 * the frozen source uses for its `lg:` desktop/mobile nav split
 * (Tailwind's lg), not Kadence's own breakpoint values, since this
 * markup is fully custom and not driven by Kadence's block responsive
 * controls.
 *
 * All custom classes (.llcb-*) — no specificity conflict with Kadence's
 * own CSS, which targets its own builder markup that this header/
 * footer override replaces entirely.
