 ## 2024-05-18 - Missing Focus Visible States on Custom Switches
 **Learning:** Custom UI controls that mimic native inputs (like pill-shaped switches for Reverse or Melodic Mode) frequently omit `focus-visible` styles, rendering them completely invisible to keyboard users when tabbing through the interface. Furthermore, developers frequently mistakenly use `aria-pressed` with `role="button"` instead of the correct `role="switch"` with `aria-checked` for these pill-shaped components.
 **Action:** Always verify that interactive custom switches not only have appropriate ARIA roles (`role="switch"`, `aria-checked`) but explicitly define `focus:outline-none focus-visible:ring-*` classes.

+## 2024-04-10 - Standardization of aria-busy on Async Import Buttons
+**Learning:** Discovered an inconsistency where some background task buttons (like the AI Song Import button) lacked the `aria-busy` attribute, while others (like RbsImportModal and SamplerPanel) correctly used it to inform screen readers of processing states.
+**Action:** Applied `aria-busy={isImporting}` to the AI Song Import button to standardise asynchronous feedback mechanisms for accessibility across all modal interfaces.
 ## 2026-04-09 - Standardize Modal Accessibility for Cloud Library
 **Learning:** The `CloudLibrary` component functioned as a modal visually but lacked standard ARIA modal attributes (`role="dialog"`, `aria-modal="true"`, `aria-labelledby`), causing screen readers to announce it incorrectly or not at all.
 **Action:** When implementing custom modals, always include `role="dialog"`, `aria-modal="true"`, an explicit `aria-labelledby` referencing a visually hidden or visible title element, and an `aria-hidden="true"` on the clickable background overlay.
