detectWordPress treated any 2xx on /wp-login.php, /wp-admin/ or /wp-config.php
as wordpress, but the http client follows redirects and many sites soft-404
(200 for every path) or catch-all redirect to their homepage. a probed path
then returns 200 without being wordpress at all, so plain static sites and
marketing pages were flagged as wordpress.
read the probed response and require one of the existing wordpress markers in
its body before counting it. a real /wp-login.php still references wp-includes
assets, so genuine detection holds.
