Pokemon and sports cards now live in one collection system with per-card cost basis, pack and box tracking, shared collections, mobile-ready screens, and eBay-aware workflows.
Shared collections
Invite family members and track personal versus shared cards.
Per-copy inventory
Keep duplicates grouped in the UI while preserving copy-level history.
Investment reporting
See spend, income, ROI, and current collection value across any date range.
Passkeys
Use a passkey for secure household access. During development you can bypass auth with `DISABLE_AUTH=true`. If the email already exists, creating a passkey here will attach the new passkey to that existing account.
