Made it exist:

Manually wrote the base of the engine that took a user’s given plant (berry) genes and weighed its worth based on its six traits. [rust (the game) genetics, iykyk]

Manually wrote code to predict the resultant trait(s) in each of the six gene slots when two plants are crossbred.

Vibe-coded a GUI with input for the user’s plant genes. Created a nice finalize button and separated the “instructions” (aka where to plant the plants you have) and the “resultants” (aka the plants you’ll breed).

Added edit/delete feature in case of a fat-finger when inputting plant genes.
