/** |

* Migration — read settings from other popular caching plugins and |
| 4 |
* translate them into xSpeed equivalents. |
| 5 |
* |
| 6 |
* Each source plugin has its own importer that returns a single |
| 7 |
* normalized patch shape: |
| 8 |
* |
| 9 |
* array<string,array> // module-slug → settings patch |
| 10 |
* |
| 11 |
* which feeds straight into update_option('xspeed_module_<slug>') |
| 12 |
* via the same write path the Recommendations module uses. |
| 13 |
* |
| 14 |
* Importers are pure: detect() reads the options table, returns |
| 15 |
* what it found (or null if the source plugin's options aren't |
| 16 |
* present). plan() turns that raw read into the patch. apply() |
| 17 |
* writes it. preview() returns plan() without writing — used by |
| 18 |
* the React panel for the "what would import" diff view. |
| 19 |
* |
| 20 |
* Adding a new source = adding a private detect_*() + plan_*() |
| 21 |
* pair, then wiring them in `sources()`. |
