Content Security Policy

Content Security Policy (CSP) is a security mechanism that helps prevent cross-site scripting (XSS), clickjacking, and other code injection attacks by controlling which resources can be loaded and executed on a Web page.

SparkleMuffin uses CSP headers to restrict inline scripts, styles, and external resources to trusted sources, improving the security posture of the application.
