A list of numbered titles with durations, under the album's cover, was
the one thing on the page carrying a word above it saying what it is.
What goes is the ink and not the element: the section is a landmark and
the page's heading structure runs through it, so the h3 stays and is
clipped the way sr-only clips -- never display:none, which would take
it out of the accessibility tree along with the layout.
