/*
 * Park+ operator panel.
 *
 * One stylesheet, no build step, no CDN: cPanel shared hosting gets a file
 * upload. Everything is in here so the page has no inline <style> and keeps
 * working under a Content-Security-Policy without 'unsafe-inline' -- that
 * header is the deploy agent's and this code assumes it is not there yet.
 * For the same reason there are no @font-face rules and no url() to a
 * foreign host: script-src 'self' is already in force and a stylesheet that
 * needs a third party would either break or force the policy open.
 *
 * Designed for a cashier's screen: dense tables, large hit targets on the
 * action buttons, and state carried by BOTH colour and text, because the
 * booth monitor is usually bad and some operators are colour blind.
 *
 * LIGHT ONLY. There is no dark palette here, and no media query that
 * follows the operating system's colour preference. The owner's
 * workstation reports a dark preference and the panel is still required to
 * be light, so following that preference would mean shipping the one
 * appearance that is not allowed. A booth monitor in
 * daylight is also the worst place for a dark interface: a light ground
 * with ink text keeps its contrast when the sun is on the glass.
 *
 * The visual system is two ideas held together:
 *   - the SHELL is airy. Soft blue-grey ground, white surfaces floating on
 *     it, small radii, shadows instead of heavy borders. Chrome should feel
 *     calm because the operator stares at it all shift.
 *   - the DATA is dense. Tables get no card padding, no boxed rows and no
 *     rounded chrome -- just hairline rules and a solid rule under the
 *     header, like a printed receipt. Someone reconciling a shift wants the
 *     most rows per screen, not the prettiest rows.
