 * Concept B — Site Report — Header & Footer Retrofit
 * Navigation & Footer Standardisation module. Extends the Phase 5 body retrofit
 * (concept-b-body.css) to the header and footer, which were out of scope at the
 * time. Same technique: override the --bc-* custom properties component-library.css
 * already reads from, scoped here to header.site-header and footer.site-footer.
