/**
 * `<Select.Popup>` — the popup container that renders the select listbox.
 * Mirrors `packages/react/src/select/popup/SelectPopup.tsx`.
 *
 * Wraps `<FloatingFocusManager>` (non-modal per React — modal semantics
 * live on the Positioner via the InternalBackdrop + scroll-lock). When a
 * `<Select.List>` child is present, the popup becomes `role="presentation"`
 * and the list element owns the listbox role; otherwise the popup itself
 * is the listbox.
 *
 * Trigger-aligned placement (`alignItemWithTrigger`) is implemented here —
 * the geometry effect measures the trigger + value + selected-item-text
 * rects and writes `positioner.style.{top,bottom,left,height,marginTop,
 * marginBottom,maxHeight}` so the selected item's text aligns with the
 * trigger's value text. The popup also wires `store.scrollUpArrowVisible` /
 * `scrollDownArrowVisible` flags (surfaced to `<Select.ScrollUpArrow>` /
 * `<Select.ScrollDownArrow>`). None of the geometry is exercisable in
 * happy-dom (0 rects); the state-machine wiring is unit-tested and the
 * math remains a browser-test gap.
