render.yaml

# Render.com blueprint.
#
# NOTE: Render web services expose HTTP only — so on Render you get the HTTP
# /send API + admin UI, but NOT the public SMTP port. Use this if your callers
# speak HTTP (or run the SMTP listener elsewhere, e.g. localhost next to your app).
# For public SMTP, prefer Fly.io (deploy/fly.toml) or a VM.
