Handle camera permission denial

The browser camera prompt can be denied, dismissed, or blocked by site permissions. The session surfaces this as a CaptureError. Treat it as a UX state, not an exception.

Full example

import { CaptureError } from '@sladeid/slade-id-sdk';
 
try {
  await session.start();
} catch (err) {
  if (err instanceof CaptureError && err.code === 'CAMERA_PERMISSION_DENIED') {
    showPermissionPrompt();
    return;
  }
  throw err;
}
 
function showPermissionPrompt(): void {
  // Your UI: explain that camera access is required and link to browser settings.
}

What can go wrong

• The user dismissed the prompt without choosing. Subsequent start() calls re-prompt on most browsers. On Safari, the user may need to clear site permissions.
• The camera is in use by another tab or application. The session emits a different error code; check err.code rather than assuming it is always permission-related.
• No camera is available at all. The session throws CaptureError with code NO_CAMERA. Surface a different message than permission-denied.
