{% comment %}
GitHub Pages doesn't let us configure redirects, so all redirecting has to be clientside.
1. This uses javascript to avoid cluttering the navigation history.
   If path is /portal/, try to preserve the rest of the URL when redirecting.
2. If javascript is not available, just redirect immediately to catch-all /we-moved
3. If the browser blocks redirects, then the user has to redirect themselves??
