/* subcore console — visual system.
 *
 * The subject is a network operations desk: servers, inbounds, quotas in bytes, expiry dates.
 * Two decisions drive everything below.
 *
 * 1. The ground is deep slate-TEAL, not black. Operators sit in this for hours next to a
 *    terminal; enamel-green instrument panels are the vernacular of the gear this product
 *    actually manages, and they are easier to read against than pure black.
 * 2. THE MONO IS THE DISPLAY FACE. Addresses, uuids, ports, byte counts and tokens are not
 *    incidental values in this tool -- they ARE the content. So they get the typographic
 *    emphasis (tabular figures, real size, letterspaced small-caps labels as instrument
 *    legends) and the Persian chrome stays quiet around them. No webfont: the CSP forbids a
 *    CDN, and the system stack renders Persian well on the operator's machine.
 *
 * Colour is a status-lamp language, used sparingly: amber means LOOK, mint means healthy,
 * red means broken. A page with no amber on it is a page with nothing to do.
