* Performance Suite — mobile touch-target sizing. |

| 13 |
* PageSpeed / accessibility flags interactive elements that are smaller than |
| 14 |
* ~48px or too close together on mobile ("Touch targets do not have sufficient |
| 15 |
* size or spacing"). This prints a small, mobile-only stylesheet that gives |
| 16 |
* aBlocks buttons and linked icons a minimum tap size. |
| 17 |
* |
| 18 |
* Opt-in via `perf_touch_targets` (default off — it nudges visual sizing, so |
| 19 |
* it's promoted only after the site owner confirms it fits their design). The |
| 20 |
* target size is filterable. |
