/* Sticky Guardian Digital Literacy Association
   ------------------------------------------------------------------
   PALETTE NOTE, not decoration: this site runs on the BLUE-AMBER axis
   only. Red-green colour deficiency affects roughly one man in twelve,
   including the director, and the blue-yellow channel stays intact
   under it. No red/green pairings anywhere, and nothing on this site
   encodes meaning in colour alone -- every coloured thing also has a
   word, a border, or a position saying the same.

   TYPE NOTE: the body face is Atkinson Hyperlegible, drawn by the
   Braille Institute for low vision, with letterforms deliberately made
   unconfusable with each other. Base size is 21px, not 16.
