 * It composes `FloatingPortal` to mount the select’s floating layer
 * relative to the select root, preventing clipping by parent containers
 * and avoiding z-index and overflow issues.
 *
 * While the select is open, `SelectPortal` wraps its children with
 * `FloatingFocusManager`, enabling managed focus behavior and ensuring
 * focus is restored correctly when the select closes, based on the
 * Floating UI context.
