Interface ViewerConfigPanelParams

DOM container; defaults to document.body.

localStorage key for persisting drag position + closed state. Defaults to "xkt-vcp-panel".

Optional helper that wires the panel's "New View" footer button and the per-View destroy buttons. When absent, both actions still work — "New View" calls Viewer.createView({}) and destroy calls view.destroy() — but the helper's per-View bookkeeping (auto-canvas, CameraFlight, controllers) is skipped.

Viewer to inspect and edit. Doubles as the WeakMap key for ViewerConfigPanel.openFor idempotence — one panel per Viewer.

Show on construction (default true).
