/* CleanVINUSA operator panel.
 *
 * Mobile first, because §6.3 of the spec is literal: part of the ticking-off
 * happens from a phone. Everything here is one column until 640px and only then
 * spreads out; the queue is built from cards rather than tables for the same
 * reason - a table with five columns and two buttons cannot be made to work on
 * a 375px screen, it can only be made to scroll.
 *
 * Served as a file, not a <style> block, so the CSP can forbid 'unsafe-inline'
 * outright instead of carving an exception for our own markup. There is no
 * script-src at all: the panel has no JavaScript.
