Everything here runs over the LAN: no LG cloud, no Nabu Casa, no rooting the TV, nothing
sideloaded onto it. Home Assistant talks to the set with the built-in webostv integration,
and Google only ever sees HA's own fulfillment.
Written up because ThinQ was a dead end for me and most of the individual pieces below are either undocumented, wrong in the obvious place, or only findable by reading the integration source.
Tested on an OLED65C56LA, firmware 33.31.68, HA 2026.7.4.
