/* WORQ Petty Cash - mobile-first.
 *
 * Built for one hand, a crumpled receipt in the other, and a phone camera:
 *  - tap targets 48px and up;
 *  - system fonts only, nothing waits on a webfont over venue wifi;
 *  - safe-area insets respected, since it runs full-screen from the home screen;
 *  - no inline styles anywhere: the page's Content-Security-Policy forbids them.
