3. Authentication Files: Expanded beyond YouTube cookies to include all auth tokens, certificates, and keys
4. Certificate Files: Added patterns for .pem, .key, .crt, .p12, .pfx files
5. API Credentials: Added patterns for api-keys.json, tokens.json, .secrets
6. Log Files: Enhanced log patterns with versioned logs
7. Temporary Files: Added temp/, tmp/, *.tmp, *.temp patterns

9. Docker Overrides: Added local docker-compose override files
10. Backup Files: Added patterns for .bak, .backup, .old, .orig
11. Cache Directories: Added .cache/, .npm/, .yarn/, *.tsbuildinfo

Security Assessment:

✅ All confidential data patterns covered ✅ Environment variables properly excluded ✅ Authentication tokens and certificates protected ✅ API keys and sensitive configs excluded ✅ Temporary and backup files ignored ✅ Build artifacts and cache properly handled

The .gitignore is now fully optimized and secure.
