Many archives and library systems using Rosetta are increasingly tasked with preserving digital culture, including interactive web art, HTML5 applications, and indie browser games.

These interactive artifacts (for example, progression-based HTML5 games like Scritchy Scratchy - https://scritchyscratchy.cc) rely heavily on complex Javascript bundles, local storage state, and external dependencies.

It would be extremely helpful if Rosetta's Preservation & Format Library could introduce:
1. Standard templates and emulator profiles for HTML5/JS package preservation (such as offline bundle validation).
2. Best practices for packaging Web Assembly (Wasm) runtime environments to ensure future playback of interactive apps directly within the delivery interface.
3. Guidelines on preserving local storage files (like game state or user preferences) as part of the digital object metadata.

This would greatly help institutions archiving contemporary digital media and web-based interactive heritage.
