## SECURITY CHECKLIST (confirm each yourself)
- [ ] No secrets, keys or tokens in client code, logs or the repository.
- [ ] Every new endpoint checks the signed-in user's workspace before reading or writing (no cross-workspace access).
- [ ] Inputs are validated on the server, not only in the browser.
- [ ] Card details never touch your servers; use the payment provider's hosted fields or page.
- [ ] Webhooks are verified with the provider's signature before anything changes.
- [ ] Amounts are computed on the server; the browser never decides what is charged.
