Per explicit feedback: swapping the whole form out for a bare success message felt wrong for "you're already signed up, nothing to do" — the form stays visible with a small red note below it instead, same as every other inline validation error. No per-form UI changes needed, they already render the error state. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
