 * toast.css — bottom-right notification stack.

 * Uses the unified premium-feel tokens from steps 2-4:
 *   --ps-elev-2 (lifted overlay shadow)
 *   --ps-ease   (Superhuman ease-out-expo)
 *   --mint family for success state
 *   --amber for warning, --red for error (shell.css status tokens, untouched
 *   by accent.css which only redirected blue+purple → mint).
