    # The email templates merchants may edit in the dashboard: the emails
    # customers receive, plus the layout and shared partials those emails are
    # built from. Staff, store-owner and seller emails are never registered, so
    # they always render from files. `spree_emails` registers its own; an
    # extension adding a customer email registers it the same way.
    #
    # @example
    #   Spree.editable_email_templates.register(
    #     'spree/loyalty_mailer/points_earned_email',
    #     kind: :email, sample: 'MyApp::EmailSamples::PointsEarned'
    #   )
