 * The "End-of-Chapter Exercises" dropdown (class chapter-exercises).

 * sphinx-togglebutton collapses a box by giving its children height: 0, but the
 * exercise boxes inside keep their bottom padding and the Answers rubric keeps
 * its bottom border, which leaves a blank band under the collapsed title.
 * Take the hidden children out of the layout instead, so the collapsed box is
 * a single title bar.  Only boxes with this class are affected.
