/* Think North — shared "motion-graphics login" chrome.
   Used by templates/accounts/login.html, signup.html, clerk_auth.html and
   templates/access/redeem.html so the four login-adjacent surfaces stop
   redeclaring four near-duplicate inline token sets. Token values mirror
   static/site/tnc.css (kept as a standalone file, not an import, so these
   pages don't have to pull in the full marketing-site stylesheet). */
