PROMPT 1 OF 3

Build a web app called Seed Swap Shelf. Let a librarian create a seed library, add seed varieties with name, crop type, days to maturity, packet count and a photo, and publish a public browsable catalog with filters by crop type.

PROMPT 2 OF 3

Add borrowing: a gardener enters name and email to check out up to five packets, which lowers stock. Later they can log a return of saved seeds with variety, quantity and harvest year, which raises stock and records the grower. Show low stock warnings to the librarian.
