     The data layer did not move and did not change. Every pin is still a vault item, still end-to-end
     encrypted, still synced; see KnownHostSecret. What is here is a screen over VaultViewModel.KnownHostPins.
+
+    v5c-3: restyled against KnownHosts.dc.html — still a main-chrome screen (the rail's own Keys item stays
+    the way in), a 40px back arrow to Keychain rather than the old link inside it, a bordered radius-12
+    container in place of the plain list-and-sidebar split, and a Copy fingerprint button beside Withdraw
+    pin. Everything the screen could do before still can: Filter, Selected, ForgetSelectedCommand and the
+    provenance notes below are unchanged, just repainted.
