Social bar position is a click-toggle, not a drag — the drag-snap misbehaved for shaky hands (snapped up but wouldn't come back down; jitter around the deadzone). Clicking the bar now flips it top/bottom via ToggleSocialBarPosition; SocialBarSnap and its units removed — 153 tests passing, 0 warnings
