NO-ob/LoliSnatcher_Droid ? reverse-engineered prompt

Build me an Android app for browsing booru imageboards that feels fast and easy to use. I want to be able to search tags, open multiple searches in separate tabs, and keep each tab’s site, tags, and scroll position independent. The app should support a lot of booru sites, show images and videos smoothly, and let me download multiple posts at once with useful options.

Please include things like favorites, filters, blacklists, and tag history, plus some way to sync settings and favorites across devices. I’d like the app to keep everything private and store data locally, with a modern Material style, dark mode, dynamic colors, and plenty of settings for layout, image sizing, and overall behavior.

If you need to look up current docs online for any APIs or Flutter details, go ahead and do that.
