A Progressive Web App (PWA) is a modern type of website designed to offer an app‑like experience while still running through a standard browser. Once installed on a device, a PWA can load more quickly, work with limited connectivity, and provide a smoother and more reliable user experience without requiring installation from an app store. It relies on contemporary web technologies such as caching and service workers to improve performance, stability, and accessibility.

The PWA for this website is currently in an early development stage. It includes the essential features required for installation and basic operation, but its architecture is still being expanded and refined. As part of this ongoing development, both ordinary and extraordinary maintenance may occasionally be necessary to test reliability, functionality, and security.

When maintenance affects only the PWA system, the installed PWA may continue to operate for a short period but may display temporary signs of malfunction, up to complete non‑functionality, until the updated version is restored. During such periods, the traditional website will continue to function normally through any standard browser, ensuring uninterrupted access to all public content.

This notice will be updated if and when the PWA system undergoes significant structural changes.
