Intrinsic ("hug-contents") layout of a tree as nested vertical stacks:
each container's size is the bottom-up sum of its children, each child is
placed top-down from its container. Unlike row/col (which fit items
into a fixed container), the containers grow to fit. Pure function of the
inputs, so feeding it a previewed tree yields a previewed layout.
