 * width gets that width, because it is the smaller value. A theme that sets
 * `100%` — which plenty do, leaving width to each block — would otherwise
 * produce a collection running the full width of a 27-inch monitor, with facet
 * labels at one edge and their counts at the other. min() reads that 100% as
 * "no opinion" and caps it.
 *
 * max() on the padding for the same reason in the other direction: the theme's
 * own root padding when it has one, and never less than 1rem, because text
 * against the window edge is the single most obvious sign that a plugin has
 * bolted its own pages onto a site.
