/* Leonardo by DarwinAI — arculati tokenek, alapok, tipográfia, gombok, kártyák, sárga blokkcímek.
   Koncepció: „kódex” — meleg papír, tinta-kék, sárgaréz-arany; vékony műszaki vonalak, regisztrációs jelek, kiadói tipográfia.
   A szín a DarwinAI-arculatból (arany, krém) és a látványtervből (tintakék blokkok, borostyán gombok) jön. */
