Dave: Upgrade alchemiter with holopad.

The totem pedestal is converted into a holographic projector. It projects an image of the item the punch code represents.

This seems useful for previewing an item a code will produce, without spending the grist on it. You test it out with the blender card.

But it still renders the alchemiter unusable. At least without further upgrades.

> Jade: Draw the totem lathe.
