Statischer Stabilitätsrand: vorzeichenbehafteter Abstand der Bodenprojektion des Schwerpunkts zum Rand des Stützpolygons (McGhee & Frank 1968).

com_xy is the COM projected onto the ground (x, y). Positive = the COM is inside the support polygon by that margin (statically stable, larger = safer); negative = outside (tipping). Returns the margin in world units (-inf if the polygon is degenerate / has no area).
★ground / contact_tol are forwarded to support_polygon — pass them (floor level z or plane [a, b, c, d]) so airborne feet are excluded. Without them the contacts are used as given and a lifted foot can turn a tipping robot into a "stable" one; pre-filter with contact_points in that case.
★2 足支持(線分)と 1 足(点)では面積が無いので -inf を返す(この値は変えない —— 変えると破壊的変更)。線分・点までの余裕が要るときは support_line_margin。Two-foot (segment) and one-foot support return -inf by contract; use support_line_margin for a finite margin there.
