/**
 * The kit component a hand-rolled control duplicates, when the kit provides
 * one.
 *
 * Two answers, and the difference between them is the whole reason the kit is
 * read rather than assumed. `Button` means the kit ships one and the
 * application built a second: a duplicate. `null` means the kit was readable
 * and has nothing like it: still a defect, because a control assembled out of
 * raw elements beside a design system is a gap in that design system, but a
 * different one, and saying "the kit provides Button" about a kit that does not
 * would send somebody looking for an export that was never there.
 *
 * When the kit could not be read at all, the name match is the only evidence
 * available and it is used, because a suspicion is what this scan produces.
