Title: Specify HTTP protocol for JS assets

The example page is more likely to be opened as a file, and not served from a web server. If we don't specify protocol (to let it be either HTTP or HTTPS),
```html

```
then it fails to load when loading from a file like this
```
file://path/to/index.html
```
