- Add Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy headers to nginx.conf for enhanced security - Create serve.json configuration file with security headers for local development - Update npm scripts to use vite preview instead of serve package for consistency - Fix PDF viewer file parameter handling to prevent fallback to default URL - Enable annotation editor mode by default in PDF viewers (annotationEditorMode: 1) - Improve PDF preference management by clearing conflicting annotation editor settings before loading - Update iframe URL construction to use URL API for proper origin handling - Refactor annotation viewer setup to use eventBus for stamp button activation instead of direct DOM manipulation - Add localStorage preference configuration for signature editor and permissions in sign tool - Enhance security posture by implementing COOP/COEP headers required for SharedArrayBuffer and cross-origin isolation
