🛡️ Sentinel: [security improvement] Harden headers and event handling#90
Conversation
… listeners This PR enhances the security posture of the application by: 1. Hardening the Content Security Policy (CSP) with `object-src 'none'` and `base-uri 'self'`. 2. Adding a `no-referrer` policy to protect user privacy and prevent information leakage. 3. Refactoring dynamic button creation to use `addEventListener` instead of `onclick` for better security and maintainability. 4. Explicitly setting `type="button"` for dynamically created buttons to prevent unintended side effects. Verified these changes using a Playwright script to ensure functional correctness and lack of CSP violations. Co-authored-by: Shin5hi <200498632+Shin5hi@users.noreply.github.com>
