#!/usr/bin/env bash
# run.sh — convenience launcher for development.
#
# Reads ./config.yaml if present, falls back to env-var-only configuration.
# Use `./run.sh dev` to run the backend with auto-reload.
#
# For production, run uvicorn (or gunicorn+uvicorn workers) directly and
# put a TLS reverse proxy in front. See README "Security notes".
