+-- 英文站新闻数据修复（同一批导入 ID 整体偏了 338）
+--
+-- A. hc_category_sub_content：栏目关联挂到了产品/解决方案
+-- B. hc_demo_product：正文扩展表 sub_id 同样偏了 338 → 详情页「内容不存在」
+-- C. hc_route：Company News(790) 详情路由 pattern 误为 d+（缺 \）→ /en/gongsixinwen/3310.html 报 code=-1
+--
+-- 真实新闻 ID = 错误 ID + 338（本地 68 条全部匹配）
+-- 栏目：788 News & Updates；子栏目 789/790/791/1097
+-- =============================================================================
+-- 执行顺序：先诊断 A/B/C → 确认 offset=338 → 备份 → 修复 → 校验
+-- 若线上 offset 不是 338，不要直接跑修复
+-- 修复 C 后还需更新 route/{siteId}_en_frontend.php 中 pattern 为 \d+，或后台重新生成路由
