 * ESL Timecard - phone first.
 *
 * The whole app is one thumb on a phone held in one hand, outdoors, often in
 * sun. So: one column, large type, a primary button that cannot be missed or
 * mis-tapped, and colour that carries meaning only alongside a word, because
 * the punch list is read at a glance and sometimes through a cracked screen.
