/*
 * The whole look of the interface, by hand, in one file.
 *
 * No Tailwind and no CSS build: the shop deploys with `docker compose up
 * --build` and nothing else, and a stylesheet that needs node to exist is a
 * stylesheet that breaks the deploy on the day the deploy has to work.
 *
 * Written mobile-first because that is where it gets used: the phone is on the
 * counter all day and the desktop only comes out at closing time. Every table
 * here turns into a stack of cards under 700px -- a shopkeeper scrolling a
 * table sideways with one thumb is a shopkeeper who stops using the screen.
