• An open lesson's header is tidier: All lessons, the group and Copy link on one line, Previous and Next on the line
  below, Previous on the left and Next on the right. On a wide screen it all fits on one line; on a phone the buttons
  read "← Previous" and "Next →".
• In the lesson list each lesson's minutes line up in a column at the right, and the "advanced" tag sits right after
  the title. When a title wraps onto two lines, the progress circle stays beside the lesson's number.
