isServicesDescendant() gates the inner-page hero on being a Services
descendant. The existing inner-page.spec.js fixtures (sample-page, etc.)
are not Services descendants, so without the bypass the hero would not
render in tests and the suite would fail.
The constant CWC_TEST_BYPASS_HERO_GATE was added in lib/extras.php for
exactly this case, but the dev site's wp-config.php is operator-managed
and cannot be modified by the theme. This note records the single line
the operator needs to add to wp-config.php, plus the rationale and a
production warning.
