Executive Summary

• Increase successful “cook-from-what-I-have” outcomes.
• Reduce food waste via expiration awareness.
• Make replenishment effortless through automated missing-ingredient lists and fulfillment actions.

Non-goals (v1)

• Multi-user household sharing and roles.
• Full grocery delivery marketplace integrations (start with export + links; iterate).
