Luis focused on enhancing the visual clarity of reachability highlighting in the wesnoth/wesnoth repository, delivering a feature that refactored the rendering pipeline to introduce distinct drawing layers for highlights and borders. Using C++ and leveraging his skills in graphics programming and UI development, he updated the team-context logic so that reachability now dynamically reflects the currently selected or hovered unit, or defaults to the viewing team. This approach improved the user experience during planning and unit movement, reduced confusion, and established a maintainable foundation for future UI enhancements. No bug fixes were recorded during this period, reflecting a focused feature delivery.
