# It is used in the `Recaptcha::Verify#verify_recaptcha` if the `response` option is not
# passed explicitly.
#
# Instead of relying on this behavior, we are extracting and passing it explicitly. This will
# make it consistent with the newer, modern reCAPTCHA verification process as it will be
# implemented via the GraphQL API and in Vue components via the native reCAPTCHA Javascript API,
# which requires that the recaptcha response param be obtained and passed explicitly.
#
# After this newer GraphQL/JS API process is fully supported by the backend, we can remove this
# (and other) HAML-specific support.
