# 把 OTA 升级包 (bundle + latest.json) 上传到 Cloudflare R2 (公开桶, 前缀 store/ota/)
# 用法: bash scripts/upload-ota-r2.sh <OTA_DIR>
#   默认 <OTA_DIR> = ota-package
# 说明:
#   - bundle 固定名 wardrobe-ota.tar.gz (与 build-ota.mjs 保持一致), 覆盖式上传
#   - latest.json 一并上传, 便于把 R2 作为 OTA 静态存储 (配合 OTA_PUBLIC_BASE 使用)
#
# 依赖环境变量 (通常来自配置注册中心 CommonExternalService / cloudflare):
#   CF_API_TOKEN     Cloudflare API token (r2/CF_API_TOKEN)
#   CF_R2_BUCKET     (可选, 默认 store)
#   CF_R2_PUBLIC_URL (可选; 若设置, 同时输出可直接给 OTA_PUBLIC_BASE 使用的下载地址)
