- expose_php=Off — hide PHP version from response headers
- allow_url_include=Off — prevent remote file inclusion
- open_basedir=/var/www:/tmp — restrict filesystem access
- disable_functions — block shell execution functions not used by the app
- Session hardening: strict_mode, httponly, secure, samesite=Lax,
use_only_cookies, 48-char session IDs with 6 bits/char
Note: allow_url_fopen left On (required by PHPMailer for SMTP streams).

Add Cache-Control: no-store to all PHP-rendered pages so the browser
never serves a stale admin/auth page from its back-forward cache.
Static assets (CSS, JS, images) keep their 30-day expiry unchanged.
Uses fastcgi_hide_header to suppress PHP's default Cache-Control
before setting the definitive header via Nginx.
