// This test checks that headers (a) have the correct heading level, (b) are the right size,
// and (c) have the correct underlining (or absence of underlining).
// The sizes may change as design changes, but try to make sure a lower header is never bigger than
// its parent headers. Also make sure lower headers don't have underlines when their parents lack
// an underline.
// Most of these sizes are set in CSS in `em` units, so here's a conversion chart based on our
// default 16px font size:
// 24px    1.5em
// 22.4px  1.4em
// 20.8px  1.3em
// 18.4px  1.15em
// 17.6px  1.1em
// 16px    1em
// 15.2px  0.95em
