## Key Implementation Details
|
|
|
|
### Aria-Live Urgency Strategy
|
|
|
|
**Polite (Non-intrusive)**
|
|
```jsx
|
|
aria-live="polite" // Waits for natural pause in speech
|
|
```
|
|
Used for:
|
|
- Regular status updates
|
|
- Output messages
|
|
- Parameter count changes
|
|
- Empty state messages
|
|
|
|
**Assertive (Interrupting)**
|
|
```jsx
|
|
aria-live="assertive" // Interrupts immediately
|
|
```
|
|
Used for:
|
|
- Error messages
|
|
- Critical alerts
|
|
- Time-sensitive notifications
|
|
|
|
### Screen-Reader-Only Content
|
|
```jsx
|
|
<div className="sr-only" aria-live="polite" role="status">
|
|
Screen reader announcement
|
|
</div>
|
|
```
|
|
- Visually hidden with `sr-only` class
|
|
- Available to screen readers
|
|
- Doesn't impact layout or performance
