New nodes: Converter and Randomizer
Both are consumables — instead of being placed on the grid, you drag them onto a node you’ve already placed.
Converter — changes a node’s port and data color to the color you choose, so you can re-route a build without tearing it down
Randomizer — gives a chance to upgrade the node to a higher tier

Accumulator — more rewarding overall. Each tracked stat has been rebalanced relative to the others, and tiers now have a cap to keep them from running away
