   Structure: hero (big logo + tagline) -> Who we are -> Contact
   Palette: Ink #1A1714 / Gold #CE9A3C / Light #D8A845 / Paper #FBF8F2
   Type: Inter for ALL text (via Google Fonts). The only Fraunces on the
         page is the logo wordmark, which is outlined to paths in the SVGs.
   Accent lock: gold is the only accent. No gradients, no stock-template feel.
