+// bundle that crashes on init ("d is not a function"), making /projects appear
+// empty. Mobile Safari users have no devtools to unregister manually, so this
+// SW is shipped specifically to self-destruct on activation:
+//   1. unregister itself
+//   2. delete every cache it ever opened
+//   3. force every open client to reload from the network
+//
+// Browsers re-fetch sw.js on every navigation (we send Cache-Control: no-cache
+// from the Go handler), so this propagates the moment a user opens any page.
+// A proper versioned SW will land in a follow-up commit (Step 2) once the
+// underlying bundle bug is fixed.
