+// and change every release, but browsers heuristically cache this entry

+// chunk names the update deleted → 404 → the strategy dashboard dies until
+// a hard refresh. The `?v=` makes the URL change with the release, so a
+// fresh entry always pulls its matching chunks. BUNDLE_VERSION is inlined
+// by esbuild — the built shim keeps its zero-import guarantee.
