# F9 报表设计器协议宿主
# 注册表 HKCR\f9designer\shell\open\command 指向本脚本：

# 前端唤起：ReportDesign.vue 的 openGridDesigner()
#   f9designer://open?base=<origin>&rid=<报表Id>&token=<jwt>&code=<报表编号>
#
# 流程：解析协议参数 -> 下载模板 .grf -> 用锐浪 Grid++Report 7 设计器打开(阻塞等待关闭)
#       -> 关闭后把模板回传后端 -> 清理临时文件
# 日志：tools/report-designer/logs/designer_yyyyMMdd.log（排查"点了没反应"时看这里）
