/* ============================================================
 * Wiman IoT — operator UI
 * ============================================================
 * Design principles:
 *   - Industrial: dense, information-rich, no decorative noise
 *   - Trustworthy: subdued palette, restrained typography
 *   - Operator-first: high contrast for at-a-glance reading
 *   - Status colors used only for state (green/amber/red/gray)
 *
 * Token system below — every spacing/color/shadow comes from a var.
