Create a modern and visually stunning login page template for a web app. The design should include: Gradient text for headings or titles (use trendy color gradients like blue-to-purple or pink-to-orange). A clean and minimalist layout with a central login card or container. Glassmorphism or subtle neomorphism effects for input fields and buttons. A responsive layout suitable for desktop and mobile screens. Include modern Google Fonts for typography (e.g., Inter, Poppins, or Montserrat). Include placeholder elements for "Forgot password", Sign Up, and Social Login options. Use modern CSS features like flexbox, grid, and transitions/hover effects. Style the page with a dark/light mode toggle if possible.
