Toast

<%# Markup for the toast demo.
    The single source used for both the live render and the copy-paste code.
    stimeo--toast provides max-count management, WAI-ARIA live region support, and
    pausing the auto-dismiss timer on hover or keyboard focus.

    Showing a toast is done with attributes alone (no hand-written JS):
    put data-action="click->stimeo--toast#show" plus
    data-stimeo--toast-body-param / data-stimeo--toast-type-param on the trigger button.
    For advanced cases where you want to trigger it remotely from JS, the controller
    element keeps show->stimeo--toast#show, so CustomEvent('show', { detail }) works too. %>
