test(review): floating is a judging criterion now, and the judge applies it

The spawn-view expectation states that nothing may float and that a shadow more than a hand's
width below an object means the object is floating. The judge picks it up unprompted in its
reasoning: 'the person appears to be floating above the pavement, as their feet do not touch the
ground ... shadows do not align correctly with the objects'.

That is the criterion working. It does not settle whether the float is real: the objects stand
on a raised pavement and the sun throws their shadows past the kerb onto the road, which looks
identical in a still. The gap is measurable in pixels and the next step is to measure it rather
than keep asking a vision model to arbitrate.

Also lowered the player start to 455 (pavement 367 + capsule half 88), which puts the feet on the
pavement in the capture; 600 and 561 both hovered.
