/* Cornello English — design system.
   Layout: a study desk — course rail on the left (tab bar on phones), one wide working column;
   English material is set like a dictionary page (serif + IPA), Russian UI in a plain sans.
   Visual language: cool paper and ink blue; yellow highlighter marks words you are learning,
   a blue underline marks new words, subtitle yellow belongs to the player. */
