   ONVI — ukážka A2 · „Špecifikačný hárok"

   Žiadne kartičky. Štruktúru drží 12-stĺpcová mriežka a vlásočnicové
   linky: mono popiska vľavo, obsah vpravo — všetko na tých istých
   koľajniciach, takže nič nikde nepláva.

   Jediný orámovaný objekt na stránke je okno ONVI Monitor, lebo to
   naozaj zobrazuje obrazovku.

   Písmo: Instrument Serif na nadpisy (jediná ozdoba stránky),
   Instrument Sans na text, JetBrains Mono na dáta a popisky.
