THIS PAGE ONLY READS. It calls receiveFeatureReport()
(HID GET_FEATURE) and never sendFeatureReport() (HID SET_FEATURE).
A GET_FEATURE control transfer cannot modify the mouse's stored settings, so
this page cannot brick, misconfigure, or alter the mouse in any way.
It does not touch firmware. Nothing is written to flash.
The write APIs are additionally shadowed at runtime (see enforceReadOnly()).
