 * Two constraints shape everything below and neither is decoration.
 *
 * Colour never carries meaning alone. A free date is blue and also says "4
 * free"; a date nobody can take is grey and also says "None free". There is no
 * red and no green anywhere in this file, so nothing in the interface depends
 * on telling those two apart.
 *
 * Nothing loads from a network. No web font, no icon set, no analytics. The
 * program is meant to run on a laptop in an office with bad wifi and look the
 * same as it does anywhere else.
