"""Speed authority between a locator socket client and the GUI field.

The data_processor uses the speed a socket client streams unless the live config
sets `ignore_socket_speed`; then `gpr_speed_m_s` from the GUI field applies. Each
GPR-like page (gpr, legacy_gpr, sar3d) has its own checkbox and field, and the
field is editable only while it is the one in force.
