/* Packfit. A check-in-desk calm: warm paper, a boarding-pass blue you read the
   answer in, amber when a bag is over, green when it fits. Big inputs, a plain
   yes or no per bag, fine on a phone while you stand on the bathroom scales with
   a suitcase. Shares the look of the rest of Johan's small tools. */
