   MedMint — About Page (Production SaaS Redesign)
   Inspired by: Vercel, Linear, Notion, GitHub, Stripe, Apple, Duolingo
   Design principles: clean, premium, minimal, soft shadows, rounded
   corners, smooth gradients, glassmorphism accents, micro-animations,
   scroll reveals. Uses existing MedMint design tokens (teal/mint).
