Uiua
A bit late getting to this, but happy with this solution, despite it being nothing more than just building/summing all paths. As usual, you can drop your own file onto that solution.

Curse my inability to think bottom-up and array-oriented at the same time!
When I compare it to some other Uiua solutions on the Discord I feel like I’m still just banging rocks together.
