   PORTED, NOT INVENTED. Every value below is copied from usenudge.app's
   stylesheet (nudge-agent-landing/styles.css). This page is deployed in two
   places (its own repo and /comparison on the site), so it carries its own copy
   rather than linking the site's 123KB stylesheet and inheriting rules written
   for a different page. `npm test` diffs the tokens against the site when the
   site repo is present next door, and fails when they drift.
