   system.css / site.css (which mean different things elsewhere). Loaded AFTER
   system.css + site.css. Colours map to the shared tokens so the page themes
   with the rest of the site; only the decorative canvases (index.js) are tuned
   for the dark default. Nav, footer and #progress live in the shared layer.
