/* ==========================================================================
   NutriAI — Vitality Flow landing page
   Tokens mirror lib/themes/colors.dart so web and app read as one product.

   Breakpoints, and only these three:
     1080px  desktop → tablet landscape (two-column layouts collapse)
      860px  tablet  → tablet portrait  (side-by-side panels stack)
      620px  phone
   Everything between them is fluid via clamp(), so there is nothing to
   re-tune when a new size shows up.
