Contributed foundational planning work to the EuroPython/website repository by adding a new sprints project entry for Pillow, complete with metadata and relevant links. Focused on documentation using Markdown, the work outlined a cross-language implementation plan for introducing planar image storage in Pillow’s core imaging object, addressing both C and Python layers as referenced in Pillow issue #1888. This planning established clear traceability between the project entry and the related commit, ensuring future development efforts are well-documented and coordinated. The contribution emphasized structured documentation practices and cross-language design, laying the groundwork for subsequent technical enhancements in Pillow’s image processing capabilities.
