+// 边界（重要）：
+// 1) 本文件只做**菜单分组**——不改路由 path、不改页面、不改 API、不改 DB；
+// 2) 权限仍由 permission.ts 的 MENU_ITEMS.roles 过滤 + ROLE_ROUTES/hasRouteAccess 判定，
+// zone A/B 只作权限维度，不作菜单维度；
+// 3) 页面条目的文案/图标/roles 一律取自 permission.ts（MENU_ITEMS），本文件只写 path 关系；
+// 4) 未在本文件登记的菜单项不会消失——MainLayout 兜底归入 900 域「未归类」；
+// 5) 回退开关：localStorage.cma_menu_mode = 'pdca' 或 URL ?menu=pdca 即还原原 PDCA 五组。
