araveai99-glitch/ExecuAI ? reverse-engineered prompt

Build me a clean Next.js web app for a product called ExecuAI.

I want a polished homepage and a simple app feel, using the design system that is already in the repo. Make it look modern and professional, with a strong hero section, clear calls to action, and a few sections that explain what the product does and why someone would use it. If it makes sense, add a basic dashboard style layout too, so the project feels like the start of a real SaaS app instead of just a landing page.

Please keep the code organized and make sure it runs well with the existing project setup. Use the current docs online if you need to check anything about Next.js or the related tools already in the repo. If there are places where a backend or database connection would normally go, leave sensible placeholders so it can be expanded later.
