   BANSAL SNAX — STYLESHEET
   =========================================================================
   Design language: premium, organic, export-quality. Clean lines, generous
   whitespace, a forest-green + warm-mustard-gold palette on a soft cream
   background — built to read as a modern international food brand rather
   than a conventional namkeen website.
