/**
 * Device-flow (QR activation) view — K1-lite "MOSTRAR QR".
 * 10-foot layout on the fixed 1920x1080 canvas (viewport.js scales it).
 * Telco visual style: deep navy field + violet/orange accents. Rendered by
 * login-page.js only when Config.DEVICE_FLOW_ENABLED is true, so with the flag
 * OFF none of these classes are ever used.
