January 2026 (2026-01) monthly summary for Khan/wonder-blocks. Delivered two major feature streams: Modal Dialogs UX Improvements and DatePicker modernization/localization. Modal work refined scroll behavior on small-height screens and enabled closing by clicking outside the content, including through a padding layer, reducing friction in modal flows. DatePicker migration moved to Wonder Blocks DatePicker, upgrading date handling to react-day-picker and Temporal, with robust localization support and accessibility improvements across locales. These efforts yield smoother user interactions, stronger internationalization coverage, and a more maintainable, design-system-aligned codebase. Key commits provide traceability to feature delivery (see f6457be382538145e4f27a67ae43dcdee08dda15, 673432cbb4e246ab922be7480ae623a62e739440, d6ae5fb895136adccd9746a3c4e928c302882900, 07c38eccb5fc10654ccc78d7754e7cd0cd920cd6, 0cce8bfcaa65a9b5f09f2a0d351f67810f3463a1).
