I've configured the modern design tokens in globals.css with deep, refined colors for a sophisticated dark interface. The new chat-specific tokens include glassmorphism effects, violet-blue AI accent colors, and refined surface elevations. The page.tsx is set up to render the PA Assistant component centered on a dark canvas.

I've implemented the entire PA Assistant chat window as a single, cohesive component that modernizes the original design. It features a sophisticated dark glassmorphism aesthetic with animated tab switching, glowing AI accents, and a refined layout for messages and input. The design strictly uses raw CSS/Tailwind patterns and Lucide icons without relying on shadcn components.

The PA Assistant has been modernized with a high-end dark theme featuring glassmorphism effects and sophisticated micro-interactions. The new design includes an animated tab switcher for "Chat" and "Insights," glowing AI accents, and a refined floating input area. All components were built using pure Tailwind CSS and custom design tokens to ensure a premium look without relying on external libraries.

I've transformed the PA Assistant into a fully modern, high-end interface with enhanced design tokens, animated thinking states, and refined message bubbles. The chat now displays a complete conversation flow with a user message and an AI thinking response featuring animated dots. All interactive elements include smooth transitions, gradient accents, and glassmorphism effects for a premium aesthetic.

I have created the app/page.tsx file and added the required default export to render the PAAssistant component. This resolves the import error and sets up the main entry point for the application.
