# =============================================================================
# start.sh —— Linux / WSL / macOS 一键启动脚本。
#
# 与 start.ps1 同样四步,只是 shell 改 bash:
#   1) docker compose build
#   2) docker compose up -d
#   3) docker exec ...  bash build.sh
#   4) docker exec ...  source install/setup.bash && bash
# =============================================================================

set -euo pipefail  # 出错即停;严格变量未定义检查;管道失败传播。
cd "$(dirname "$0")"  # 切到本脚本所在目录(确保 docker-compose.yml 路径对)。
