Interface FloatingPanelBaseParams

CSS class-name prefix used by the subclass's stylesheet (e.g. "xkt-sh"). The base only uses it to compose the ${prefix}-dragging class added to _header while a drag is in flight.

DOM container for the panel + pill. Defaults to document.body.

Minimum height the resize handles will allow, in CSS pixels. Default 200.

Minimum width the resize handles will allow, in CSS pixels. Default 280.

When true, the panel renders as a centered modal: a translucent backdrop sits behind the panel while it's visible, intercepts pointer events from anything else, and dismisses the panel on click or Escape. Subclass owns the centering CSS (top: 50%; left: 50%; transform: translate(-50%, -50%)).

When true (the default), eight invisible drag handles (4 edges + 4 corners) are injected into _panel and the user can resize it. Resize is suppressed when modal is true. Panels that wrap a fixed-size child (NavCube) or whose internal layout doesn't tolerate width changes (Toolbar) opt out by passing false.

localStorage key for the panel's drag-position + closed state. Each subclass picks a unique value (e.g. "xkt-sh-panel") so two different panels don't share a slot.

Z-index tier the panel lives in. "view" panels (hosted Views) always sit beneath "default" panels (regular demo panels and dialogs); within each tier panels still reorder on click via bringFloatingPanelToFront. Defaults to "default". See studio/floatingPanelZ for the counter ranges.
