/* ===========================================================================
 * RETAIL ENGINEER — SUITE THEME
 * One skin for the whole estate: platform, Queue, Displays, Shifts & Leave,
 * Inventory, Ticketing, Mailing, Webmail.
 *
 * Served from the platform at /suite/suite-theme.css (vendor a copy per
 * engine if you prefer no cross-app fetch). Adopt in two steps:
 *   1. <link rel="stylesheet" href="/suite/suite-theme.css">
 *   2. <script src="/suite/suite-switcher.js" defer></script>
 * Tokens land on :root, so an engine inherits the palette even before its
 * components move to the .re-* classes.
 *
 * Sources of truth: Wave 19 design-tokens.css (the platform) + the unified
 * shell developed in retail-engineer-next (aurora identity, hero bands,
 * stat tiles, bar-race viz). If a screen disagrees with this file, the
 * screen is wrong.
