/* Quiet, crisp, monochrome. Built to read on a phone between jobs.
 *
 * The colourway is white and black and nothing else: colour is spent only
 * where it carries meaning - a failure, a success, a contact tier - and even
 * then it is muted, because a page that shouts everywhere emphasises nothing.
 *
 * Two Apple habits are worth naming because they are load-bearing rather than
 * decorative. The header is translucent and blurs what scrolls under it, so
 * the page reads as one surface with a sheet floating over it rather than two
 * stacked blocks. And every control is a pill with a real pressed state,
 * because on a touch screen the only feedback you get is the one you draw.
