   Flint Engine microsite — isolated stylesheet
   Scoped under the `.fe` root / `.fe-*` class prefixes so it can

   Phase 10 — visual redesign. Modern ecommerce / product aesthetic:
   clean surfaces, strong typography, restrained brand color, subtle
   borders + shadows, consistent radius, polished hover states.
