/*
 * HPAY point of sale (/hpay/pos). Layered on base.css, paylink.css and hpayTools.css: the same black and red, one accent, no new
 * palette, no new font.
 *
 * Direction (hartii-ui-craft, written before the code):
 *   subject    a counter terminal that takes QUAI for a price typed in dollars.
 *   audience   a shop owner or cashier on a phone or tablet, hands busy, a customer waiting; and the customer who scans the code.
 *   one job    type a price, show the code, know from the chain the moment the money has really arrived.
 *   mood       steady, exact, and loud only when the money is in.
 *   signature  the whole screen turns green and a check is drawn in dots, one dot after another, only when a payment is confirmed
 *              on the chain. Nothing on this page is green for any other reason.
 * Roles: red = the one primary action (Charge) and a payment being confirmed; green = money has arrived; amber = needs a look or
 * a storage warning; grey = over. Numbers use tabular figures. Spacing runs on 4 and 8. Touch targets are at least 44px, and the
 * keys and the Charge button at least 64px.
