/* The provenance line under every figure used to be styled here, by `p > em:only-child`, on the
 * reasoning that no other paragraph in the book is written as nothing but emphasis.
 *
 * That selector does not mean what it reads as. `:only-child` counts *element* children and
 * ignores text nodes, so it matched every paragraph containing one emphasis and no other inline
 * element -- which is a great many of them. "It is much harder to be able to *find out* -- on a
 * machine in front of you" put `find out` on its own line, at 0.78rem and 72% opacity, in the
 * middle of a sentence.
 *
 * CSS cannot express "this paragraph is entirely emphasis": there is no way to require the
 * absence of text nodes. Styling it properly needs a real class on the element, which means the
 * renderer emitting one and `scripts/build-pdf.py` gaining a branch for it. Until that is done
 * the line renders at body weight, which is how it read for the whole of the book's life before
 * the attempt, and is wrong in a way that costs nothing. */
