/* Prof. Dr. Youssef Ben Hatit
   Layout: the name over a dark blue rule, then the opening paragraph beside the portrait, then one section per
   subject, each with its heading in a left column and dates in a narrow column beside the entries.
   Below about 40rem everything is one column, and the dates sit above their entries.
   Type and colours follow the European Laser Academy's site. */
