I would've expected empty Shiny server contexts to be allowed:

    ```{r}
    #| context: server
    ```

But if the server context is empty (or contains only whitespace), you get this error:

```
Error in shiny_prerendered_app(target_file, render_args = render_args) :
  No server contexts or server.R available for density-contours.qmd
```

With `server: shiny`, server context cannot be empty
