Contributed to the Orange-OpenSource/a11y-guidelines repository by enhancing the Accessibility Checklist to improve reliability for users with disabilities. The work involved replacing animation-based tests with reflow tests across eleven essential checks, reducing reliance on motion and ensuring content remains accessible to assistive technologies. This update required careful JSON manipulation to revise French checklist result descriptions and maintain robust test coverage. The approach emphasized manual and accessibility testing, with collaboration evident through co-authored commits. The changes addressed the need for more dependable accessibility validation, focusing on usability improvements and clear documentation within the checklist’s JSON structure over the course of the month.
