canopy-dotmatrix: reconstructing davidluft.com's dot-matrix window

Reconstructs the dot-matrix window on davidluft.com from its public JavaScript bundle and scene payloads. A JavaScript engine decodes six-bit temporal-delta luminance and color fields, then renders individually animated dots; an interactive page and frame exporter demonstrate the result. The author reports comparing output with browser screenshots.
