Security: Comprehensive security hardening
- Add DOMPurify sanitization to apps (textDemo, personaDemo, unityDemo) - All user/AI content now sanitized before innerHTML insertion - Prevents XSS attacks from malicious input or AI responses - Add Content Security Policy to all main HTML pages - Restricts script/style/font/image sources to trusted domains - Blocks clickjacking with frame-ancestors 'none' - Add Subresource Integrity (SRI) to external CDN resources - Protects against CDN tampering and supply chain attacks - Added to marked.js, DOMPurify, highlight.js - Create _headers file for security headers - X-Frame-Options: SAMEORIGIN - X-Content-Type-Options: nosniff - X-XSS-Protection: 1; mode=block - Referrer-Policy: strict-origin-when-cross-origin - Permissions-Policy for camera/microphone/geolocation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
