Animated toast notifications to copy

Notifications that enter, inform and leave without getting in the way: an elastic success toast, a toast with undo, one with progress, an error toast that shakes, a message toast, several toasts stacked, a compact island, a calendar reminder, a connection-status toast and one with two actions.

Use them to confirm a save, warn about an error or offer an undo. Adjust colours and timing live and copy the code.
