New analytical overlay based on an exponentially tilted arcsine distribution in ArcSine Drift Board, improving accuracy and providing smooth, controllable bias in the drift curve.

Keep the previous histogram distribution in grey as a reference for the current histogram distribution.

Fixed an issue with the ball dropping animation in the ArcSine board.

Added minimum success probability constraint to improve truncated distribution approximation in Pascal and Negative Binomial boards.

Fixed an issue with ball alignment after ball settling. Balls now fall simultaneously rather than sequentially, improving simulation speed.

Displays a single trajectory line within the triangle to provide an intuitive visualisation of how the balls interact with the pegs and are sorted into bins.

Added Pascal, Poisson, and Negative Binomial distributions. Displays a single trajectory line within the triangle to provide an intuitive visualisation of how the balls interact with the pegs and are sorted into bins.

Added ArcSine and Geometric distributions, and a new scaled binomial simulation feature.

Explicitly label the right Y-axis as the count of falling balls and draw the histogram dynamically.
