   Colours come from the brand kit (brand/palette.md): Sun Clay #E37C45,
   Night Ink #16151B and White. The neutrals, the text colours, the link
   colour and the corner radii are the tokens of the app's window
   (internal/ui/web/app.css in the app). The site is flat: no gradients,
   glows or shadows, so it has none of the window's shadows.
   Sun Clay is never used for text on light backgrounds (2.9:1); light
   pages use --link (#A84C1A) for links instead, and dark pages a lighter
   #EE8A52. */
