Now I'll update the globals.css to use the blue primary accent (#155EEF) and create the complete landing page with all sections. Let me also update the layout metadata.

Now I'll create the complete landing page:

I've built the complete FNP Mastery landing page with all five sections you requested:

1. Editorial Hero — Features the headline "Pass your FNP boards the first time" with a compelling subhead about AANP/ANCC certification prep and the single primary CTA "Start studying free"
2. Social Proof Strip — Displays the three key stats (4,000+ questions, 500k+ nurses, 93% pass rate) in a clean horizontal layout
3. Feature Grid — Five features with Lucide icons, each with a title and one-line description covering Adaptive QBank, In-depth Rationales, Personalized Study Plan, Progress Analytics, and Study Offline
4. Testimonials — Two realistic nurse testimonials with names, credentials (MSN, FNP-BC and DNP, FNP-C), and initials avatars
5. Closing CTA Band — Blue background section repeating the primary action with inverted button styling

The page uses your blue primary accent (#155EEF converted to oklch), maintains generous spacing throughout, is fully mobile-first responsive, and includes proper accessibility features like ARIA labels, semantic HTML landmarks, and visible focus states.
