character: a seated body is held by its seat alone - no step to the walker while sitting, and a hold no longer turns it off the seat's heading

Browse source 
The user's play of the bundle: the character shook while seated. chr_sit_tick eased the body onto the
seat point at the ground's height, then the same frame's chr_travel handed it to the walker, which
pushed it off a log, a bench or a boulder beside the seat; the next frame pulled it back. Unwalked, the
game's walker parks as it does under a rider. A hold's turn toward the work fought the seat's yaw the
same way. The new test sits the body against the boulder: 4.63 m from a seat at 5.7 before, still after.
