Let me read the current codebase to understand the existing structure before making changes.

Now let me read the rest of sections.tsx (lines 532+):

Now I have the full picture. I need to:

1. Add 4 new sections (Case Studies, Why Nexora, Testimonials, CTA) to sections.tsx
2. Update page.tsx to include them in the correct order
3. Update the Navbar to include new nav links

Let me generate placeholder images for the case studies, then add the new sections:

Now I'll add the 4 new section components before the Footer in sections.tsx, and update the Navbar and page:

Now add the 4 new sections before the Footer:

Now update the page.tsx to the new section order:

Four new professional sections have been added to the Nexora portfolio while preserving the existing theme, spacing, and animation system. Case Studies uses a two-column alternating layout with generated dashboard screenshots and a clear Problem/Solution/Outcome typography hierarchy. Why Nexora presents four feature blocks in a responsive 2x2 grid with the same glassmorphic card style. Testimonials features two clean blockquote cards with a decorative gradient quotation mark. CTA is a bold full-width section with a slightly darker background and centered glow, featuring the two requested buttons. The final page order matches exactly: Hero, About, Services, Case Studies, Why Nexora, Testimonials, CTA, Contact, Footer.

Let me read the current codebase to understand what needs to be updated.

Now let me read the remaining sections (Contact, Footer, and the new sections added previously):

Now I have the full picture. I need to:

1. Update the contact email to manikandanprabhu37@gmail.com and wire the contact form to send via mailto:
2. Create the CM Assistant floating chatbot component
3. Update the page to include it

Let me first update the contact email in sections.tsx:

Now update the contact form to actually send via mailto with the form data:

Now let me create the CM Assistant component:

Now update page.tsx to include the CM Assistant:

Both changes are complete. The contact email is now connected to manikandanprabhu37@gmail.com throughout the site -- the contact form uses mailto: to open the user's email client with pre-filled name, email, and message fields, and the email display link is also updated. The CM Assistant is a lightweight floating chatbot in the bottom-right corner with a gradient "CM" button, a polished dark-themed chat window, typing animation, quick suggestion chips, and keyword-based responses covering all requested topics (about, projects, skills, contact, freelance, resume, services, individual project details). No external APIs or heavy libraries are used -- just structured keyword matching for fast, reliable responses.
