Pin VPS deploy to /root/periscope only.

Refuse update-periscope.sh unless dirname resolves to the canonical
checkout, set compose project name periscope, and document that the
GitHub clone URL may still be manvalan/pinscope.

 ### Update a live instance (e.g. periscope.michelebigi.it)
 
-On the server, from the Periscope checkout:
+One checkout on the VPS: **`/root/periscope`**. The GitHub clone URL may still be `manvalan/pinscope`; clone into that path so the folder is not `pinscope`:
 
 ```bash
+git clone git@github.com:manvalan/pinscope.git /root/periscope
+```
+
+Do not keep a second live tree under `/root/pinscope` (or `/opt/pinscope`). Stop compose there, then deploy only from the canonical root:
+
+```bash
+cd /root/periscope
 ./scripts/update-periscope.sh
 ```
 
-The script pulls the current branch, writes `NEXT_PUBLIC_API_URL` / `CORS_ORIGINS` for `https://periscope.michelebigi.it`, rebuilds both Docker images, and leaves `data/` alone. First run: put `DEEPSEEK_API_KEY` in `.env` at the repo root (compose reads that file). `--no-pull` skips git. `SITE=https://other.host ./scripts/update-periscope.sh` overrides the public URL.
+The script cds via `dirname "$0"/..` (no `find`). It refuses to run if the resolved root is not `/root/periscope`. Compose project name is `periscope`. It pulls the current branch, writes `NEXT_PUBLIC_API_URL` / `CORS_ORIGINS` for `https://periscope.michelebigi.it`, rebuilds both Docker images, and leaves `data/` alone. First run: put `DEEPSEEK_API_KEY` in `.env` at the repo root (compose reads that file). `--no-pull` skips git. `SITE=https://other.host ./scripts/update-periscope.sh` overrides the public URL.
 
 Do not set `ENVIRONMENT=production` unless Clerk auth is configured — that flag refuses to boot with auth disabled.
