/**
 * The token contract, read inside a class list joined by hand (UIG-42):
 *
 *   <div className={['text-sm', open && 'bg-gray-100'].join(' ')} />
 *
 * The Tailwind plugin stops at a function call, so it never reads the list in
 * front of `.join(' ')`, and no setting can make it: a call it is told about is
 * read at its arguments, which here is the `' '`. This rule reads the list and
 * tests each class against the same patterns, with the same messages, as the
 * rule it stands in for. It registers once per rule it mirrors, so an error
 * stays an error and a warning a warning (`token-joined/classes`, `/values`,
 * `/spacing`).
 *
 * A list joined with anything but one space is not a class list, and a
 * sentence built this way passes unless one of its words is itself such a
 * class, as in `'set text-sm here'`. Only strings written in the list are
 * read, directly or behind `cond && …`, `a ? … : …` and a template's fixed
 * parts; a list worked out while it runs cannot be read.
