Month: 2026-04 — betagouv/mon-service-securise: Delivered targeted UI/UX polish for the service and risk management interfaces, achieving clearer layout, improved readability, and consistent styling across padding, max widths, modals, sliders, typography, and copy. Implemented through a series of frontend commits focused on visual polish and usability (e.g., modal behavior improvements, removal of extra slider steps, text size adjustments, and copy fixes). Fixed a test bug in expiration date calculation to correctly account for the 61-day edge case when the first day of the month is involved, ensuring reliable expiry logic. Overall impact: reduced UI defects, improved user experience, and more robust business logic for expiry calculations. Key points: - Frontend UI/UX polish across service and risk management interfaces - Improved modal behavior to prevent background scroll and ensure smooth open/close - Simplified slider flow by removing intermediate steps and tightening typography - Consistent copy and table styling for better readability - Fixed expiration date calculation test bug to cover 61-day edge cases
