Add help-osk-docs stack: Zensical instructions site for 05-osk

Static instructions site for client 05 served at help.osk.team. Markdown +
images built by Zensical (zensical build) into public/, served by nginx behind
Traefik. Content is bind-mounted from /mnt/containers/help-osk-docs (absolute
host path — Portainer GitOps can't resolve relative mounts). Adds the
help/help-osk router+service to traefik/dynamic/web.yml (TLS via Let's Encrypt,
public/open).

+# help-osk-docs — instructions site for client 05
+
+Public static site at **https://help.osk.team** with user instructions, written
+in Markdown and built with [Zensical](https://github.com/zensical/zensical)
+(static-site generator from the Material for MkDocs team). Served by `nginx`
+behind the existing Traefik reverse proxy.
+
+## How it works
+
+- `docs/` — Markdown pages (+ `docs/assets/` for images). **This is the content.**
+- `zensical.toml` — site config (name, nav, theme, Markdown extensions).
+- `nginx.conf` — static web-server config.
+- `docker-compose.yaml` — two services:
+  - `help-osk-build` — Zensical image, one-shot: runs `zensical build --clean`,
+    rendering `docs/` → `public/`, then exits. (The Zensical image is a
+    builder, **not** a host server — by design.)
+  - `help-osk` — `nginx:alpine`, serves `public/`, joins `reverseproxy-nw`.
+    Starts only after the build succeeds.
+- Traefik terminates TLS for `help.osk.team` (Let's Encrypt) and proxies to the
+  `help-osk` container. Router/service live in
+  `../traefik/dynamic/web.yml` (`help` / `help-osk`).
+
+## Bind-mount / host-sync (important)
+
+Content is **bind-mounted**, and Portainer GitOps can't bind-mount the
+repo checkout (relative paths resolve inside Portainer's container and become
+empty dirs). So the project must exist on the host at an absolute path —
+exactly like the Traefik config. This git repo is the **source of truth**.
+
+Sync the project to the host (excluding the generated `public/`):
+
+```sh
+rsync -a --delete --exclude 'public/' \
+  help-osk-docs/ <docker-host>:/mnt/containers/help-osk-docs/
+```
+
+The `help-osk-build` container creates `/mnt/containers/help-osk-docs/public`
+on the host during the build.
+
+## Deploy (Portainer)
+
+1. DNS: `help.osk.team` → public edge IP, reachable on :80 (Let's Encrypt
+   http-01). *(Done.)*
+2. Sync this folder to `/mnt/containers/help-osk-docs/` on the docker host
+   (see above).
+3. Make sure the Traefik `help` router/service in `../traefik/dynamic/web.yml`
+   is also synced to the host dynamic dir
+   (`/mnt/containers/traefik/container-data/dynamic/web.yml`). Traefik's file
+   provider (`watch: true`) picks it up live — no Traefik restart needed.
+4. In Portainer, add a stack pointing at `help-osk-docs/docker-compose.yaml`
+   (or redeploy the existing stack). The builder runs, then nginx comes up.
+
+## Add or edit an instruction
+
+1. Add/edit a Markdown file in `docs/` (e.g. `docs/nastrojka-vpn.md`).
+2. Put images in `docs/assets/`, reference them: `![alt](assets/file.png)`
+   (size with `![alt](assets/file.png){ width="600" }`).
+3. Add the page to `nav` in `zensical.toml`.
+4. Commit, re-sync to the host (step 2 above), redeploy the stack in Portainer
+   (re-runs the build; nginx serves the updated `public/`).
+
+## Local preview (optional)
+
+```sh
+# Build and inspect output
+docker run --rm -v "$PWD":/docs:Z zensical/zensical build --clean
+# Live preview on http://localhost:8000
+docker run --rm -p 8000:8000 -v "$PWD":/docs zensical/zensical
