   AI Flash Lab — site layer
   Sits on top of the Stanford design system tokens in /ds/styles.css.
   Nothing here overrides a Stanford brand rule; the identity bar, wordmark and
   global footer follow Decanter exactly.

   Origin: "Direction A / Field Guide" from the Stanford Design System project
   on claude.ai/design (mocks/flashlab). Extended with the patterns the rest of
   the site needs — boost cards, filters, prose, tables, FAQ, mobile nav.
