Very good. Small moves left on the board.

Reads as a fully realized veggie panini, six of six roles, most layers have a partner.

The seven flavor axes of the whole sandwich, each summed across its layers. The shaded ring is the catalog's middle 80%; the small number under each axis is where this sandwich falls in the catalog. A shape that sits inside the ring is in the range most sandwiches live in; a spike past it is where this one stands apart.

Points: what the Sandwich Score would lose if that one layer were left out, everything else the same. A negative number means the sandwich scores higher without it. Flavor runs 0 to 5 on each axis.
