Create a 404 page with the same theme as the site #20
Description
Implement a custom 404 error page that matches the current theme and design of the Openln-Engine site. The 404 page should provide a user-friendly message, keep users within the site experience, and offer navigation options (e.g., a link back to the homepage or main sections).
Requirements:
- Design the 404 page to visually align with the existing site theme (colors, fonts, layout).
- Add a helpful message indicating the page was not found.
- Include navigation options to guide users back to the main content.
- Ensure the 404 page is responsive and accessible.
This will improve user experience and maintain consistency across the platform.
