docs/aria: Add best practices for direct ARIA on components

Document the pattern of applying ARIA attributes directly to Ant Design
components that support them, rather than wrapping in unnecessary divs.

Example:
- ✅ <Space.Compact role="region" aria-label="Zoom controls">
- ❌ <div role="region"><Space.Compact>

Also note that components should forward ARIA props to their DOM elements.

 **Build Status**: ✅ Build successful (pnpm build-dev in packages/static)
+
+### Best Practice Notes
+
+1. **Direct ARIA on Components**: When Ant Design components (Space.Compact, Button, etc.) support ARIA attributes, apply them directly without wrapping in divs:
+   - ✅ `<Space.Compact role="region" aria-label="Zoom controls">`
+   - ❌ `<div role="region"><Space.Compact>` (unnecessary nesting)
+
+2. **Component Props Support**: All frontend components should be checked to ensure they forward ARIA attributes to their DOM elements. The Icon component was enhanced to support ARIA props for broader accessibility support.
+
+3. **Live Regions**: Use `aria-live="polite"` for status updates and `aria-live="assertive"` only for urgent alerts. Always test with screen readers to ensure announcements are clear.
