/* Motor selector.
 *
 * Only what system.css does not already carry: the grouped requirement form,
 * the per-candidate readout, and the version stamp under a result. Every class
 * is prefixed .selector-, every colour is a system token, and nothing here is
 * decorative. No shadow, no glow, no lift, no entrance animation: the result
 * region is present and readable from the first byte of HTML.
