+**Learning:** [Initial file creation]
+**Action:** [N/A]
+
+## 2024-05-15 - [Toggle Buttons Accessibility]
+
+**Learning:** Elements functioning as standalone toggle buttons must use the `aria-pressed` attribute to indicate their toggled state to screen readers, allowing users to understand when a button is selected or active.
+**Action:** Consistently add `aria-pressed` to toggle buttons instead of relying only on visual selection state.
