Worked on the mrdoob/three.js repository to improve the quality of the Chinese documentation by addressing a specific typo in the fundamentals.html file. Focused on enhancing documentation accuracy and accessibility for Chinese-speaking users, the contribution involved careful review and correction of language errors using HTML and documentation best practices. The change was implemented with clear commit hygiene, referencing the related issue for traceability and maintaining project standards. Although no new features were added, the targeted bug fix reduced potential confusion for developers relying on the Chinese docs, supporting a smoother onboarding process and ensuring that fundamental concepts are accurately conveyed.
