Create a secure Admin Panel page within the current project, reusing the existing design system, Tailwind setup, and layout conventions—do not create a new project or alter public-facing pages. The admin panel should be accessible via protected routes (e.g., /admin) and include authentication-based access control. Build a clean, modern dashboard UI that allows authorized admins to manage site content including pages (Home, About, Courses, 11+ Preparation, Franchise, Contact), courses, testimonials, and media assets, and to view and manage parent enquiries and franchise applications. Include dashboard overview cards (total enquiries, recent submissions), editable content sections (CMS-style forms), status tracking for enquiries, and basic analytics placeholders. Ensure role-based permissions (Admin / Editor), form validation, audit-safe updates, and future CMS extensibility. The admin UI should be responsive, accessible, and consistent with the site’s premium academic branding, and implemented only as new admin pages and components without impacting existing public routes.
