Events

Event	Detail
mlf-submit-request	User requested submit. Cancelable by the primitive layer.
mlf-submit-start	{ form, state } after submission starts.
mlf-submit-success	{ form, state, result } after successful submit.
mlf-submit-abort	Abort notification for a canceled submit.
mlf-submit-error	{ form, state, error, status } after a failed submit.

mounted.host.addEventListener("mlf-submit-success", (event) => {
  const detail = (event as CustomEvent).detail;
  console.log(detail.result.meta);
});

Prefer engine hooks for business logic. Use primitive events when integrating with host DOM systems.
