The package.json and package-lock.json files have been updated to include new development tools: Prettier, its Astro and TailwindCSS plugins, and a package called preline. The tailwind.config.mjs file has also been updated to reference preline and its plugin as well as to enable Tailwind's dark mode feature.
This commit includes the introduction of Astro project setup files, including the configuration. The main change is the addition of the configuration file `astro.config.mjs`, where Tailwind is set up for Astro integration. It also adds `.gitignore` files, a `package.json`, and setup files for VSCode and IntelliJ IDEA. The project includes a favicon and a simple Astro page. It comes with a `package-lock.json` file which locks down the versions of each dependency ensuring that installs generate the exact same tree across machines.
