test(placement): the player stands on Road_Hollywood, not on the sidewalk

Three spawn heights - 455, 395, 469 - produced identical captures, and the in-game probe names
the surface every time: mesh=Road_Hollywood at Z 366. The north sidewalk exists, carries
collision and its top is Z 380, so the character stands 14 cm BELOW the pavement and reads as
floating against the kerb; its shadow falls on the road because the road is genuinely lower.

That is why lowering the spawn changed nothing: the capsule falls through to the road whatever
height it starts at. The question left is the player start's XY footprint, not its Z - the
sidewalk is right there but the capsule never lands on it.

Player start set to 469 (sidewalk top 380 + capsule half 88 + 1) so that, once the footprint is
fixed, the height is already right.
