# The server exposes GET /healthz (verified against the built image's
# composed Starlette routes: /rpc, /.well-known/agent-card.json,
# /extendedAgentCard, /healthz).
# Tuned for a slow-start server under load. A startupProbe gives it time to
# clone tenants + boot before liveness/readiness apply; liveness is tolerant
# (5s timeout, 6 failures × 30s) so a briefly-slow /healthz doesn't restart it
# (was killing the pod on the default 1s timeout under cluster strain).
