+## 2025-05-22 - [Enhancing Task Empty States]
+**Learning:** Initial exploration revealed that empty states for tasks were text-only and lacked visual hierarchy. Additionally, interactive toggle elements for task descriptions and subtasks were missing `aria-expanded` attributes, which hinders accessibility for screen reader users.
+**Action:** Use visually rich empty states with icons and descriptive headings to improve engagement, and ensure all toggleable UI elements explicitly manage their expanded state via ARIA attributes.
