/*
 * The cashier's screens: right to left, Arabic first, built for a finger on a counter tablet — large targets,
 * high contrast, nothing that needs a hover. No inline style anywhere (the CSP allows styles from the till's own
 * files only) and no colour literal in this file: every colour is a token of tokens.css (POS-UX1), so the
 * light and dark themes and the six accents apply to the shift, refund and back-office screens as to the sale.
 *
 * The sale screen's own layouts are sale.css; its sheets and keypad, overlay.css; the settings preview, look.css.
