Configuration and domains
Environment variables, memory limits and custom domains.

Configuration lives with the application resource. A change takes effect on the next deployment, because the container is immutable while it runs. Some variable names are blocked because they would let a tenant reach outside its own runtime.
Memory
The configured memory value is a hard ceiling enforced by the kernel, with no swap. Set it from measured usage under load, not from optimism, and leave headroom for garbage collection spikes.
Domains
An application is reachable at its platform hostname. Pointing your own domain at it is a DNS change plus a certificate issued on the server; the dashboard shows the current state rather than assuming success.
