Ally Accessibility wraps AudioIgniter JSON endpoint in tags and breaks playlists

### Description

I found a reproducible compatibility issue between Ally Accessibility and AudioIgniter.

Environment:

WordPress
Ally Accessibility
AudioIgniter + AudioIgniter Pro

Issue:

AudioIgniter uses a JSON endpoint:

?audioigniter_playlist_id=77090

Expected output:

[{"title":"..."}]

Actual output with Ally enabled:

As a result, AudioIgniter fails to parse the response and playlists remain in loading state.

Browser console error:

Unexpected token '<', "[{"titl"... is not valid JSON

Verification:

Ally disabled → valid JSON output, playlists work
Ally enabled → JSON wrapped in paragraph tags, playlists fail

I isolated the conflict using WordPress Health Check Troubleshooting Mode and activating plugins one by one.

It appears that Ally processes a JSON response as page content and adds paragraph tags.

Expected behaviour:

Ally should ignore JSON/AJAX/API responses and only process actual page content.

Thank you.

**Actual behavior:**

When Ally Accessibility is enabled, AudioIgniter playlist JSON responses are modified by adding HTML paragraph tags.

This causes AudioIgniter to fail parsing the response and playlists no longer load.

Browser console error:

Unexpected token '<' ... is not valid JSON

The issue was isolated using WordPress Health Check Troubleshooting Mode and reproduced consistently by enabling/disabling Ally Accessibility.

### Steps to reproduce

1. Install and activate Ally Accessibility.

2. Install and activate AudioIgniter (and AudioIgniter Pro).

3. Create an AudioIgniter playlist containing one or more audio tracks.

4. Open the AudioIgniter playlist endpoint:

?audioigniter_playlist_id=

5. Observe the endpoint output.

6. With Ally disabled, the endpoint returns valid JSON:

[{"title":"Track 1", ...}]

7. Enable Ally Accessibility.

8. Reload the same endpoint.

9. Observe that the JSON response is modified and wrapped in HTML paragraph tags:

[{"title":"Track 1", ...}]

10. Open a page containing the AudioIgniter playlist.

11. The playlist remains in a loading state and browser console shows:

Unexpected token '<' ... is not valid JSON

12. Disable Ally Accessibility again.

13. The endpoint returns valid JSON and AudioIgniter playlists work normally.

### Expected behavior

Ally Accessibility should not modify JSON responses, API responses, AJAX responses, or other non-HTML endpoint output.

The AudioIgniter playlist endpoint should continue to return valid JSON without additional HTML tags or formatting.

Expected output:

[{"title":"Track 1", ...}]

Actual output with Ally enabled:

[{"title":"Track 1", ...}]
