/* No, Pero Why? educator editions (production/editions-spec.md, sections 2.2, 2.5 and 5.3).
   A sheet is landscape letter: 1056 x 816 CSS px with a 24 px margin. The student page sits on the left at 72.727%
   (593.45 x 768), then a 20 px gutter and the educator column (about 394 px). Nothing in the column passes y = 792.
   Educator text is 14.67/20 (11 pt). Answers on the student page are blue italic 20.5 px (11.2 pt after reduction). */
