August 2025 monthly summary for cedarcode/mi_carrera: Focused on stabilizing authentication tests and elevating the sign-in user experience. Implemented a virtual authenticator for Passkeys testing to improve reliability and test isolation, removed unused stub credentials and SinonJS, and updated Capybara configuration for consistent test environments. Refactored sign-in UI to be mobile-first and responsive using Tailwind CSS utilities, delivering a more usable and visually consistent sign-in experience across devices. No major bugs fixed this month; primary value delivered came from a stronger release confidence through a more robust test suite and a smoother mobile sign-in flow.
