The databases live in Docker volumes (not in git), so teammates on a fresh
boot saw an empty system. backups/procurement.dump + casdoor.dump are exact
pg_dump snapshots of the current demo state (users/roles, projects,
warehouses, quotes with receipts, inventory rows; Casdoor org/app/users);
restore.ps1 / restore.sh replace both DBs with the committed state
(--clean --if-exists, verified by a round-trip restore into throwaway DBs).
README documents how to restore and how to take a fresh dump.
