fix(ai): smaller top-anchored chevron (no clip) + primary Manage account (PR #51 feedback)

- Hero: shrink the mark 212->182px and absolutely position it 12px from the top so the chevron
  peak clears the modal's rounded edge; only the lower soft circles bleed now, never the chevron.
- Manage account is the accent-filled primary CTA on paid plans (stays quiet on free tier, where
  the Upgrade button owns the accent).
