What gets stored

Five verified ZIP packages are saved to IndexedDB. No extracted duplicate is created, keeping storage and startup memory lower.

Completed packages are detected by manifest version and size. If a download stops, start again to resume from the last completed package.

After installation

When every package is ready, close this tab and open index.html. The game will load from the local cache.
