fix(nav+story): About pill always-on-mobile, Blog desktop-only, remove author block

MarketingNav:
- About: always visible on all breakpoints; styled as outlined rose pill
  (border-rose-300, rose-600 text) — pairs naturally with the solid rose
  CTA button beside it; hover fills bg-rose-50
- Blog: hidden on mobile (sm:inline-flex), plain text gray-600 → rose-600
- Use ml-auto mr-3 on nav so links sit right of center, next to the button

Homepage FounderStory:
- Remove 👨‍💻 / Manohar Gupta / Founder block — author details move to About
- Story content and amber card remain unchanged
