    # `data-error-summary` is the hook the global turbo:submit-end handler
    # (client/js/crm/setup/turbo_config.js) uses to scroll the page back to
    # this summary after a 422 form submission, so a user who clicked Save
    # at the bottom of a long form actually sees that validation failed.
    #
    # The inline `scroll-margin-top` clears the fixed CRM navbar so the
    # alert lands fully visible — the browser honours scroll-margin-top
    # during scrollIntoView().
