nginx sent index.html with no Cache-Control, so a browser could keep it after a deploy and ask for hashed assets the new build no longer has, and show an empty page. location / now adds Cache-Control: no-cache, which covers its try_files fallback to /index.html, and includes security-headers.conf again, since its own add_header drops the server's. /assets/ and the locations passed to the backend are unchanged. script/frontend-viewport-test fails unless / and a path that falls back to the page carry Cache-Control: no-cache and Content-Security-Policy, which stands for the security headers. Model: opus-5-5
