Dante is a production-ready Astro theme for single-author blogs and portfolios. It provides a complete static site with dark/light mode, pagination, tag filtering, RSS feed, sitemap, SEO metadata (Open Graph, Twitter Cards), a subscription form, and a hero section. The architecture follows Astro's content collections pattern: Markdown/MDX files in `src/content/` are loaded via schemas defined in `src/content.config.ts`, rendered by Astro components in `src/components/`, and assembled into pages in `src/pages/`. Styling uses Tailwind CSS v4 with custom design tokens and a typography plugin. The theme is configured through a single `src/data/site-config.ts` file that controls navigation, social links, hero content, and newsletter settings. It integrates with `@astrojs/mdx`, `@astrojs/rss`, and `@astrojs/sitemap` for extended functionality. The codebase is well-structured, with clear separation of concerns, reusable components, and modern Astro practices (image optimization, pagination, content validation). It is not a library or framework but a template that can be forked and customized.
