/** |

* AI Privacy module — the GDPR off-switch FEATURES.md §AI row 6 |
| 4 |
* mandates ship in Free, regardless of whether the user has Pro |
| 5 |
* installed. |
| 6 |
* |
| 7 |
* Why this lives in Free even though every AI feature is Pro: privacy |
| 8 |
* is a fundamental user right, not a paid feature. If a site activates |
| 9 |
* xSpeed Pro and starts collecting navigation patterns / Web Vitals |
| 10 |
* for AI analysis, the GDPR off-switch must already be present and |
| 11 |
* configured — not gated behind a license. So this module ships with |
| 12 |
* Free and exposes a public filter that every Pro AI feature checks |
| 13 |
* before recording any data point. |
| 14 |
* |
| 15 |
* Pro consumes this via: |
| 16 |
* if ( ! apply_filters( 'xspeed_ai_can_collect_data', true ) ) return; |
| 17 |
* |
| 18 |
* When Pro is not installed, the module still works (the toggle just |
| 19 |
* has no consumer) — same pattern as our other Free/Pro contracts. |
| 20 |
