Fabien delivered LaTeX rendering support for the left-curve/left-curve documentation by integrating mdbook-katex, focusing on enhancing the clarity and usability of math-heavy content. The work involved adding and configuring dependencies, updating the build system, and making targeted corrections to Rust code examples and documentation text. By improving Markdown-based documentation and ensuring accurate formula display, Fabien addressed common sources of reader confusion and streamlined onboarding for new users. The changes were production-ready, with an emphasis on technical writing quality and maintainability. This contribution demonstrated proficiency in Rust, build systems, and documentation best practices, though no major bugs were addressed.
