/* Documentation layout for humanrounds.org/docs.

   Structure borrowed from docs.plane.so — a persistent grouped sidebar on the
   left, one prose column, screenshots that open large. Everything else is the
   Human Rounds paper/vermillion system: this file only adds layout, it never
   redefines a colour, a font or a control that landing.css already owns.
   landing.css must be loaded first. */
