- base image -> nginxinc/nginx-unprivileged:1.28-alpine, digest-pinned (BREAKING for the docker path: container port 80 -> 8080; compose mapping/healthcheck updated in the same change, cap_add dropped) - nginx add_header inheritance fix: shared snippets file re-included in every location that sets Cache-Control -- previously ALL security headers were dropped on real responses (verified live before/after) - server_tokens off; set_real_ip_from restricted to 127.0.0.1 - expires directives removed (duplicated Cache-Control); gzip_types text/html redundancy removed (nginx -t warn)
