/* ThingsToDo interface.
 *
 * Written for a phone held in one hand, and widened from there. Two rules
 * shape most of what follows:
 *
 *   * nothing has a fixed pixel width, and every flex or grid child that holds text
 *     carries min-width: 0. Task names, list names and usernames are written by
 *     people, and one of them will be forty characters with no spaces in it. Without
 *     those two, that one name decides the width of the whole document and the fixed
 *     bottom navigation slides off the screen with it;
 *
 *   * the tap targets on the list screen are large, because they are used while
 *     walking, holding a basket, with one thumb.
 *
 * Both themes are defined here in full. The light one is not an afterthought: half
 * of the use of this app happens under supermarket strip lighting.
