- Add authentication state detection using useSupabaseContext
- Detect embed page context using window.location.pathname
- Show 'Login' button with redirect parameter for unauthenticated users or embed pages
- Keep 'Go home' button for authenticated users without asset access
- Include current URL as redirect parameter in login link
