+## Interactive Desktop And WebVNC
+
+Prefer WebVNC for human inspection because the browser portal can preload the
+lease VNC password and avoids a native VNC client's copy/paste/password dance.
+Use native `crabbox vnc` only when WebVNC is unavailable, the browser portal is
+broken, or the user explicitly wants a local VNC client.
+
+Common desktop flow:
+
+```sh
+../crabbox/bin/crabbox warmup --provider hetzner --desktop --browser --class standard --idle-timeout 60m --ttl 240m
+../crabbox/bin/crabbox desktop launch --provider hetzner --id <cbx_id-or-slug> --browser --url https://example.com --webvnc --open
+```
+
+Useful WebVNC commands:
+
+```sh
+../crabbox/bin/crabbox webvnc --provider hetzner --id <cbx_id-or-slug> --open
+../crabbox/bin/crabbox webvnc --provider hetzner --id <cbx_id-or-slug> --daemon --open
+../crabbox/bin/crabbox webvnc --provider hetzner --id <cbx_id-or-slug> --status
+../crabbox/bin/crabbox webvnc --provider hetzner --id <cbx_id-or-slug> --stop
+../crabbox/bin/crabbox screenshot --provider hetzner --id <cbx_id-or-slug> --output desktop.png
+```
+
+`desktop launch --webvnc --open` is usually the nicest one-shot: it starts the
+browser/app inside the visible session, bridges the lease into the authenticated
+WebVNC portal, and opens the portal. Keep browsers windowed for human QA; use
+`--fullscreen` only for capture/video workflows.

 Keep the fallback narrow. First decide whether the failure is Crabbox itself,
