+## 2025-03-05 - Missing aria-busy on loading buttons
+
+**Learning:** Found several buttons across the app (like refresh/sync/export buttons) that implement loading states with visual spinners or loading text, but fail to inform screen readers of their "busy" state via the \`aria-busy\` attribute.
+**Action:** Always add \`aria-busy={isLoading ? 'true' : undefined}\` to any interactive element that displays a loading state, ensuring the loading process is exposed to assistive technologies.
