I want the Feature-Policy and Expect-CT response headers properly added—or updated if they already exist—on my WordPress site. No new plugins may be installed; please work through core files, .htaccess, functions.php, or any of the plugins that are already present if they can handle the task. The site already serves a Content Security Policy, so your solution must keep that intact and conflict-free. You will receive full FTP credentials the moment we start. Once the headers are live, I need a detailed report that shows: • exactly what you changed and where • verification screenshots or curl outputs confirming both headers are delivered on all pages • a brief note on how your implementation coexists with the current CSP Everything has to fit within my tight $5 allocation, so please keep the work focused and efficient.
