FirefoxCSS-Store is a static community catalog for discovering and sharing Firefox userChrome.css themes. It is built with Astro 7, TypeScript 6, and Zod 4. The site renders a gallery of published themes with search, tag filtering, and sorting, and generates detail pages and a /themes.json API endpoint. The repository includes a comprehensive set of automation scripts for theme submissions (issue-form → candidate PR → approval), monthly repository audits, and stats refresh. Theme entries are validated with a strict Zod schema. The codebase is well-maintained, uses modern tooling, and has active CI/CD via GitHub Actions. It is primarily an application (static site generator + automation workflows) rather than a data pipeline.
