#!/usr/bin/env bash
# dev.sh — Start ParleyLab dev servers on Linux
#
# Usage:  ./dev.sh
#
# This script:
#   1. Kills anything already on ports 8000 / 3000
#   2. Starts the FastAPI backend in the CURRENT terminal
#   3. Opens a SEPARATE terminal for live LLM usage logs
#   4. Opens a SEPARATE terminal for the Next.js frontend
#
# Requirements: gnome-terminal (default on Ubuntu/GNOME), or xterm as fallback.
