What it is
A monthly money product on its own host: overview, transactions, budgets, pots, and bills. Sign in and create account sit on that same host.
Why it exists
Challenge screens are not the same as keeping that person’s records. The loop needed its own store.
How it works
Production persists one person’s changes in a dedicated Postgres database. Seeded first-use data later belongs only to that account. History holds signup, sign in, and the five monthly pages.
