What's happening here
This is the web dashboard at app.stash.so. Users land here after signing up and installing the extension. The left rail shows their collections (Instagram's own "Saved" is basically one giant collection with no structure — this is where the real organization happens), and the main grid is every post the extension has captured. Clicking a card opens the slide-over where they can re-tag, move collections, or archive. Search goes across handles, tags, and their own notes.
The "Extension ● connected" status badge in the top right is a critical trust signal — users need to know the capture-on-save pipeline is alive. If the extension gets disabled or signed out, the badge turns amber.
