Via html-proofer, let's make sure we didn't goof our generated HTML; e.g. doesn't have any broken links.

Run it at least once, then consider adding this check to the build pipeline.

Things to lint

• Site map is valid and recent
• CSS is valid
• HTML is valid
• Links are not broken
• Spell check

Have this check run once a week, particularly for broken links.

Not necessary for a first port. We can do this as tech debt.
