Now I'll update the layout metadata and globals.css with the blue medical-education aesthetic, then create the complete NCLEX Question of the Day page.

I've built a complete NCLEX Question of the Day content page with all sections fully implemented:

1. Eyebrow header with "NCLEX Question of the Day" and today's date
2. A clinically accurate prioritization question featuring four patients with realistic clinical presentations — the correct answer (D) involves hyperkalemia with neurological symptoms, a genuine medical emergency

3. Reveal the answer section using a collapsible that shows:

   • The correct answer with a success banner
   • A thorough clinical rationale explaining why hyperkalemia is the priority (ABCs, cardiac dysrhythmia risk)
   • Individual explanations for each distractor, covering expected post-op findings, exertional vs. resting dyspnea, and non-emergent hyperglycemia
4. Key Takeaway callout reinforcing the clinical principle about hyperkalemia and cardiac function
5. One soft CTA — "Get a new NCLEX question every day — start free"

The design uses your blue primary accent (#155EEF approximated in oklch) on a light background with generous spacing, calm typography, and full accessibility (semantic HTML landmarks, ARIA labels, visible focus states, proper heading hierarchy, and screen-reader text where needed).
