     Palette: cool navy structure + warm bronze accent, on a light base.
     Navy and red are sampled from the supplied logo artwork
     (assets/img/logo-wordmark.webp). The warm bronze and cream surfaces take
     their cue from the reference palette — the warm/cool interplay is what
     makes the scheme read as a publication rather than a product page.
     Red is held back for the mark and primary actions so it never competes
     with the semantic "stop" colour used for prohibitions.
