name: OTA Package Only

# 手动触发: 前端已改但不想等全量 Android 构建 / 不想整镜像重部署时,
# 只重建 dist + minisign 签名, 通过服务端 admin 接口直推运行中的容器
# (容器挂载卷 wardrobe-ota:/app/ota-package, 设备下次轮询立即热更新, 后端/APK 均不动)
#
# 前置 (一次性, 配置中心 service-wardrobe/ota):
#   - MINISIGN_PRIVATE_KEY : 私钥 (整段 .key 内容, 多行)
#   - OTA_ADMIN_TOKEN      : 上传鉴权 token (单行, 与容器环境变量一致)
