There is no Litestore server. Your customer data sits in a database you run.
Customers, orders and payment records live in a Postgres you administer. There is no telemetry endpoint and no vendor dashboard.
Sign-in is by emailed magic link for admins and customers, so there is no password store to breach and no reset flow to social-engineer.
Admin access is read fresh from the database each time, so a ban or downgrade takes effect on the next request.
Critical modules log create, update and delete with the actor attached, so 'who changed this price' has an answer.
These are database constraints, not conventions the code tries to follow.
The parts you are responsible for.
Patching
The host, the database and the runtime, on your schedule.
Backups
A database dump is yours to take and yours to test restoring.
Secrets
The keys in the environment contract are managed by you.
Network
TLS, access control, and whatever your compliance regime asks.
