<!-- TODO(thor): confirm canonical domain (rivrsystems.com vs www). See BLOCKED_ON_THOR.md.
     Polish 4 / Task 9: Added <lastmod> per spec; switched URLs to clean
     paths (no .html) matching the spec's canonical format. Server-side
     URL rewrite is still TBD; until then both forms resolve, but the
     pretty URLs are what we want indexed. -->
