Every interaction captures a snapshot of the current spiral into a dedicated buffer with a 33% transparency weight, creating a deep, resonant history of the sequence's growth. Upon ending the auction, the piece undergoes a destructive 'aging' process—inverting the values, stripping the color, and introducing a noise-based grain that mimics the texture of an ancient fresco. This transition freezes the algorithm into a final, minted state labeled with its unique Fibonacci bid
