A plain tooltip vanished the instant the pointer left, where M3 keeps one for
1.5s and shows only one at a time — these are popover="manual", so nothing was
closing the last one. A rich tooltip's bubble was never associated with its
trigger at all, so the explanation it exists to give was never announced; the
script now writes aria-describedby (and aria-haspopup/aria-expanded when it is
persistent) onto the focusable control in the trigger slot, and again after a
morph. Plan step 18, actions.md ACT-22, ACT-25.

<x-toast> hosts the snackbar queue for the Toasts concern and
window.materialToast(), one at a time, paused on hover and focus, with
an optional action; it listens from the moment its script loads, so a
toast dispatched before Alpine starts is shown rather than lost.
<x-badge> is M3's dot and count, plus a tonal or outlined status label;
<x-rich-tooltip> is transient or persistent; <x-alert>, <x-stat> and
<x-empty-state> are built from M3's parts.
