This repository is a personal technical blog by frontend engineer fouber, containing a collection of markdown articles and design assets (PSD files, images) focused on frontend engineering, performance optimization, static resource management, and build tool design (e.g., FIS). It is not a software application, library, or data pipeline; it is a static knowledge base. The codebase consists solely of documentation and binary design files, with no executable code, tests, or build scripts. The content is insightful but the repository is unmaintained since 2019 and references outdated tools and practices.
