//
// Hover mode (popupMode: false, default):
// Parent drives visibility via showPanel. Panel auto-closes when showPanel
// drops, with a 50ms debounce. Reports panelHovered back to parent.
// Pass anchorItem for lazy position computation on each show.
//
// Popup mode (popupMode: true):
// Shows immediately on creation. Stays open until click-outside or
// dismiss() call. Emits dismissed() when closed — caller's LazyLoader
// sets active: false. Pass anchorX (screen-relative centre x).
