/* ─── Toast / snackbar ─────────────────────────────────────────────────
   Transient status messages (form success, add-to-cart, errors). NOT an
   overlay: no focus trap, no background inert — it must NEVER steal focus.
   Announced via an aria-live region (polite default; assertive for errors).
   Created + managed by hzo.toast() in toast.js. Reuses the alert status colours;
   zero new tokens. The empty region is click-through; toasts re-enable pointer
   events so their dismiss button works. */
