   Colours and type come from the theme, which lives in the `theme` block
   of js/config.js and is edited under Appearance in the rating tool.
   generate-data.js writes the actual values into a <style> block in
   index.html; the fallbacks after each comma below are what you get if
   that block is ever missing.

   Each piece of text has its own set of --t-* variables (font, size,
   weight, spacing, transform, style) so headings, menu links, captions
   and so on can be changed independently.
