render.yaml

# Minimal Render Blueprint for the Aporia backend. Deploys
# docker/backend.Dockerfile (repo root as build context, matching
# docker-compose.yml's convention - see that file's header comment) as a
# single web service. The frontend is deployed separately, natively, on
# Vercel (no Docker there) - not part of this blueprint.
#
# Render injects PORT automatically; the Dockerfile CMD already reads it
# (see docker/backend.Dockerfile). Secrets/environment-specific values are
# `sync: false` so they're set once via Render's dashboard, not committed
# here or synced from git.
