Snow rollers
WorldOwner-side snow growth requires Deep North, nonzero snow interaction flag and a heightmap. Snow-mask depth and object height produce an unclamped depth factor; Grow adds scaleGain*factor and weightGain*factor once per Update, without delta time. If current scale.x already exceeds the maximum, the next Grow clamps scale and returns before adding mass.

Identical authored gameplay configurations share one table. Disabled children, conditional activation, live state and the linked mechanics can change whether these values apply; these are not measured outcomes.
