Sep 1, 2025For 2025-09, delivered a new Landing Page Footer with Dynamic Link Rendering and Localization for Cashier. The links render from a centralized landingPageLinks config, enabling easy maintenance and localization. The footer is responsive (vertical on mobile, horizontal on larger screens) to improve navigation and accessibility. This work reduces future localization effort, accelerates feature rollout, and improves user trust with visible policy links. No major bugs fixed this month; the focus was on feature delivery, maintainability, and code quality improvements.
