   SUCCESSFIED — Design System v2
   Premium SaaS direction. Teal-anchored (from brand logo),
   deep indigo neutrals, coral as a sparing secondary accent.
   Inspired by Linear / Stripe / Notion / Groww discipline:
   one confident accent color, generous whitespace, crisp
   surfaces, restrained motion.
