AstroPaper is a highly polished, actively maintained Astro blog theme that functions as a static site generator template. It ingests Markdown/MDX content from `src/content/posts/` and `src/content/pages/` and renders a fully featured blog using Astro v7, Tailwind CSS v4, and TypeScript v6. The architecture is a monolith built on Astro's Content Layer API, Fonts API, and View Transitions. Key features derived from the source code include static search via Pagefind, dynamic OG image generation using Satori and Sharp, a lightweight i18n layer with string extraction, RTL support, subdirectory deployment support, and a highly customizable typed configuration system (`astro-paper.config.ts`). The codebase demonstrates strong engineering practices with clean, isolated utility functions, a well-defined config layer, and proactive adoption of the latest framework features. It is not a data research project.
