**Redeploy after code changes:**
Re-run Tasks 1–4. For frontend-only changes, skip Task 2.
+
+**Frontend-only redeploy (verified 2026-06-22):**
+The active WSL checkout is at `/home/cc/InternetProject` (not the `/mnt/f/...`
+path in the original tasks above). Since the Rust process serves `static/` from
+disk, a frontend-only change needs **no server restart** — just rebuild and
+replace the static files:
+```bash
+cd /home/cc/InternetProject/Client
+npm run build
+# clear stale hashed assets so old bundles don't accumulate
+ssh root@8.130.143.54 "rm -rf /opt/internet-project/static/assets && mkdir -p /opt/internet-project/static"
+scp -r dist/* root@8.130.143.54:/opt/internet-project/static/
+# verify live
+curl -s http://8.130.143.54:8548/ | grep -o '[^<]*'
+curl -s -o /dev/null -w '%{http_code}\n' http://8.130.143.54:8548/api/client/health
+```
+
+**Restart the Rust binary (backend changes):**
+A helper exists on the server: `/opt/internet-project/restart_rust.sh`. The
+previous binary is kept as `RustServer.bak` for rollback.
