What is Tailwind CSS and why is it necessary for this error?

Tailwind CSS is a utility-first CSS framework. It allows developers to rapidly style web pages by composing small, reusable CSS classes. The `@tailwindcss/typography` plugin enhances Tailwind CSS with specific typographic styles and features. Without it, you won't have the necessary components for advanced text formatting and styling within your Tailwind project, leading to the module not being found.
