Inventory Link

Sync owned cards, duplicate counts, program progress, and stubs using a browser extension that reads the MLB The Show website session you are already logged into.

No inventory sync yetInstall the local sync extension scaffold, log in to MLB The Show in Chrome, then run a user-started sync.

Sync EndpointPOST inventory snapshots to /api/inventory/sync while signed in here.
Security ModelThe extension should never ask for an MLB password. It uses the browser's existing mlb26.theshow.com session and sends only inventory/program data to this site.

Extension Scaffold

I added a starter Chrome extension in the local project under extension/show-sync. It has the permissions and popup flow ready; the last missing piece is confirming the exact MLB The Show inventory API endpoints from a logged-in browser session.
