/*
 * Fleet dashboard theme.
 *
 * A control-room palette: one neutral ramp for surfaces and text, one blue
 * accent for anything interactive, and green / amber / red reserved for
 * state. Nothing glows, blurs or pulses unless it is in transition, so the
 * colours that do appear always mean something.
 *
 * Pages are laid out to fit one screen on a desktop monitor; feeds, tables
 * and the configuration sheet scroll inside their own box instead of the
 * page. Below the desktop breakpoints the page scrolls as usual.
 *
 * No rule here depends on inline styles, so the pages work under a strict
 * Content-Security-Policy.
