Nice one @victorlin! I haven't thought too hard about the entries in each list but as a v1 it looks great.

This will be a nice improvement!

Aesthetically, one thing I'd point out (in addition to what James did) is that the alignment/justification of the sitemap as a whole and the columns within it feel a bit off to me. Our central layout element/block is a centered column, but we have a slew of widths for that column. Within the column, text and inline elements are either centered or left-justified.

I think the sitemap would "fit in" better with the rest of the page blocks with a reduced overall width (e.g. what the team block uses) and/or with the inner columns/blocks of the sitemap (Resources, Tools, etc) themselves centered (but keeping the text elements within them still left-justified). Something like the below.

Thanks @victorlin! (A rebase onto master might be nice before merge, but not required)

Thanks for reviewing! There's no merge conflicts and #869 is based on this, so I'll just merge as-is to avoid extra rebase churn on that PR.
