 * Multi-Window Controller — product site
 * Direction: "the operator's console" — dark, precise, telemetry-flavoured.
 * Signature: crop-mark corner brackets framing the app preview (grounded in
 * the app's per-window crop feature) + a monospace utility face for labels,
 * stats and step numbers. System fonts only; fully self-contained.
