/* ŠVP JEDNODUŠE — design system
   Direction: "sešit" (a school exercise book), anchored on the blue of the
   institute that publishes the RVP (#3566FC). Ink on paper, a blue margin rule

   write "on the line".

   "inkoustová tužka" — the indelible copying-pencil violet of Central-European
   officialdom — reserved for producing the filed artifact (export to PDF).
   --gap (red) / --covered (green) / --amber are coverage data only. */
