/* ============================================================
   Dizaxen — blood sugar support (chromium / glucose metabolism)
   Design language: STRUCTURED, PRECISE, RELIABLE. Cool/deep tech.
   Palette: cool teal + deep navy-blue + white. Stack archetype.
   Angular, grid-aligned, clinical-but-modern. Distinct from
   GlucoZen (calm soft/round): Dizaxen is deeper, cooler, more
   technical with hard edges and ruled line-work.
