Ren'Py Screen Language and Python State: Predict System Synchronization

Ren'Py uses a prediction system to instantiate screens in the background, aiming to eliminate frame drops during transitions. This mechanism analyzes script flow to pre-calculate screen states before they are explicitly shown. A potential conflict arises when a screen depends on volatile Python variables that change rapidly between the time the prediction is
