/* figade styles, shared by every page.

   COLOURS
   The first :root block is the light theme. The block under it is the dark theme,
   which browsers use when the visitor's device is set to dark mode.
   To change a colour, change it in both blocks.

     --bg       page background           --surface  the tool box, tables, buttons
     --subtle   inputs, table headings    --border   thin lines around things
     --text     normal text               --muted    quieter text
     --accent   the main button and the   --link     links
                selected size

   FONTS
   Headings use Figade Serif (a trimmed copy of Source Serif 4, in /fonts).
   Everything else uses the device's own font, so it loads instantly.

   SPACING
   Spacing sticks to steps of 4px: 4, 8, 12, 16, 24, 32, 48, 64.
