Path-only @junk matcher on upbeatbytes.com (*.php, /wp-*, /.env, /.git, /phpmyadmin,
/vendor, etc.) returns 403 instead of falling through try_files to a 200 SPA shell.
Never matches by User-Agent, so real users + Googlebot/Bing are untouched. Applied to
the live Caddyfile (validated + reloaded) and mirrored into the repo snapshot.
