TailGrids/tailgrids — reverse-engineered prompt

Build me an open source React UI library using Tailwind CSS and TypeScript. I want it to feel like a polished UI kit people can drop into a Next.js or React app, with clean customizable components such as buttons, cards, alerts, modals, dropdowns, tabs, tables, forms, date and time inputs, tooltips, toasts, navigation, pagination, avatars, badges, accordions, drawers, charts, spinners, sliders, and icons.

Make it production ready, responsive, dark mode friendly, accessible with keyboard support where it matters, and easy to theme. Include a simple docs or demo app where someone can browse components, see examples, and copy the code. Also add a small command line setup flow if reasonable, so users can initialize the library and add individual components. Keep the code lightweight and readable, and organize it like a real reusable component library. Look up current docs online if you need to.
