/**
 * Czech and Slovak birth number (rodné číslo). Since 1954 it is ten digits
 * divisible by eleven; before that, nine digits with no check at all.
 *
 * The pre-1954 form therefore verifies nothing, and reporting it as verified
 * scored every bare nine-digit number — order numbers, ticket ids — as a
 * confirmed identifier. It stays a candidate (checksumMode is 'boost', so a
 * failed check never drops anything); it just has to earn its score from the
 * words around it, like any other shape with no check digit.
