# DESC:  一次性构建 arm64 CI 镜像（MOOS-IvP + jsoncpp + GTest）。
#        构建产物缓存后，日常交叉编译只需 ./scripts/build-arm64.sh。
#
# 用法:
#   CI_TOKEN=xxx ./scripts/build-arm64-image.sh          # 构建（已存在则跳过）
#   CI_TOKEN=xxx ./scripts/build-arm64-image.sh --force  # 强制重新构建
#
# 环境变量:
#   CI_TOKEN   内网 Gitea token（拉取 moos-ivp / googletest 镜像，兼容 GITEA_TOKEN）
