+/**
+ * "More" sheet shown when the user taps the "More" tab in the mobile
+ * bottom tab bar (src/components/admin/MobileTabBar.tsx).
+ *
+ * NOTE: The primary navigation tabs (Orders / Stops / Products / Dashboard)
+ * live in the bottom tab bar itself, NOT in this sheet. This sheet
+ * intentionally exposes only the secondary operations so the tab bar can
+ * stay focused on the high-frequency workflows. If you need to add a
+ * primary tab here, do it in MobileTabBar instead.
+ *
+ * (PR 6 cutover: the v1 /admin/orders, /admin/stops, /admin/products
+ * paths now 307-redirect to /admin/v2/* via next.config.ts — see
+ * `redirects()` there.)
