"""Health endpoint — no DB or Redis touch; liveness, plus the build's identity.

The identity rides here rather than on a route of its own because it answers
at the same cost: two module constants, no I/O, nothing that can be slow or
fail. It is also already fetched app-wide — TopNav calls `refreshHealth` on
mount — so a separate endpoint would mean a second request for two strings.

Both fields are OMITTED when unset rather than sent empty. See build_info.
