/* copperbrook.co.uk: the agency's own website. Direction A (chosen 26 Oct 2026): data-led and bold.
   Deep brook green for the header and big moments, a cool off-white page, copper only where we want a
   click. Archivo (heavy, tight) for headings, Figtree for reading. Flat surfaces, thin rules, no shadows
   on ordinary cards: the example sites are the only things that float. */
