## In one paragraph

TravelHub is a multi-tenant flight-booking platform for travel agencies. Several
agencies ("tenants") share one deployment and one database, but each sees only
its own inventory, customers and revenue. An agency's staff sign in, search the
agency's flight inventory, sell tickets, manage and cancel bookings, and see a
trading dashboard. It is built as a reference sample: Angular SPA, Go API,
PostgreSQL, with strict per-tenant isolation.
