During February 2026, Petty Blue contributed to the mdn/translated-content repository by enhancing the accuracy of Japanese technical documentation. They focused on localization and documentation skills, specifically correcting the spelling of 'コンピュータ' to 'コンピューター' in proxy and tunneling notes to align with standard Japanese usage. This change, implemented in Markdown, improved readability and ensured consistency for Japanese-speaking users. Petty Blue referenced issue #33761 to maintain traceability of the update. The work addressed a targeted linguistic detail rather than broad code changes, demonstrating careful attention to documentation quality and localization standards within a limited but well-defined project scope.
