Dockerfile.backend

# Dockerfile for the Ito backend API server (local testing).
#
# Multi-stage build:
#   1. Build the `ito` binary with the `backend` feature (default).
#   2. Copy the binary into a minimal runtime image.
#
# Usage:
#   docker compose -f docker-compose.backend.yml up --build
#
# The entrypoint runs `ito backend serve` with bind 0.0.0.0 so the port is
# accessible from the Docker host.
