/* docs.cleverpoint.pro — a reading-first documentation layout.
   Brand from the logobook (teal #259578, lime #A5BB61, graphite #313131, Raleway) as in
   cleverpoint_site/static/site.css. Raleway stays for headings and navigation; long text is
   set in the system UI font, which reads better in small sizes than a display face.
   Text and links use the deeper teal #1d7a62 (5.2:1 on white); pure teal and lime are fills.
   Dark theme: follows the system, or the reader's choice stored as data-theme on <html>. */
