AI Grid Interface

Reverse-engineered paradigmai.com into a fully functional spreadsheet workspace. The interface features a collapsible sidebar for managing multiple sheets, a toolbar with an Enrich action that runs AI over selected cells, and an AG Grid Enterprise grid with custom theming, row selectors, column popovers, and drag-and-drop reordering. State flows through Zustand for sheet operations and Jotai for shell-level UI, with real-time sync powered by Cloudflare Workers and Durable Objects. Built on Next.js 16, React 19, tRPC, and Vercel AI SDK for streaming tool calls.
