+// ============================================================
+// 发布签名配置（正式包）
+//
+// 1. 生成 keystore（一次性，命令在 android/ 目录下执行）：
+//      keytool -genkey -v -keystore app/upload-keystore.jks ^
+//        -keyalg RSA -keysize 2048 -validity 10000 -alias key
+//    （会让你设两个密码 + 填公司信息；这两个密码务必保管好，
+//      丢了=正式包永远无法升级，只能换包名重新上架）
+// 2. 把密码填进 android/key.properties（该文件已被 git 忽略，不会泄漏）
+// 3. 填完后执行 flutter build apk --release / flutter build appbundle
+//
+// 兜底：key.properties 不存在或 storeFile 为空时，
+// 自动降级用 debug 签名（仅便于本机安装，不能上架/升级）。
+// ============================================================
