/* WebsiteBench project site.
   Type: EB Garamond (display), Schibsted Grotesk (UI and body), Martian Mono (numbers, routes, code).
   Colour: GitHub neutrals carry surfaces and text. The README's five theme colours are the accents, and all five stay
   in visible use: salmon, cream, mint, sky and slate. A pastel that fails contrast as text stays a fill or an icon,
   with dark ink for the text. Fonts are self-hosted (assets/fonts/OFL.txt). */
