/*
 * Tipline styles.
 *
 * The design brief is one sentence: a frightened person on a five-year-old
 * phone should be able to find the box, type in it, and press the button.
 * Everything here serves that. System fonts (no webfont request, no flash of
 * invisible text, no third-party origin), one column, large touch targets, and
 * a submit button that is never below a fold on any screen this has been opened
 * on. Dark mode is honoured because the phone being held under a table at night
 * is a real case.
