+## 2025-02-12 - Added ARIA labels to icon-only buttons
+**Learning:** Found several icon-only buttons (`<Plus />`, `<X />`) used for managing state input tags in the `ArrivalChipBar.tsx` component that lacked `aria-label`s. This is a common pattern to watch out for.
+**Action:** When finding inline controls that look like tags or chips, verify that any interactive, icon-only buttons within them have clear, descriptive `aria-label`s.
