Worked on the miraheze/mw-config repository to deliver a new configuration feature for mobile UI management within wiki namespaces. Developed a PHP-based solution that introduced the wgMFNamespacesWithoutCollapsibleSections option, allowing administrators to disable collapsible sections for specific namespaces such as File, Category, Special, and Media. This approach addressed the deprecation of wgMFCollapseSectionsByDefault while maintaining compatibility with existing defaults. Focused on configuration management and wiki administration, the work emphasized maintainability and future extensibility for namespace-level UI behavior. No major bugs were addressed during this period, with efforts concentrated on enhancing mobile usability and laying groundwork for further UI customization.
