🎬 Open a video → see its frames - pure C#

The fourth domain, closing the loop. The suite renders frames into an animation; here those bytes are decoded back by real 1.6 container decoders (Gif.Decode + Apng.Decode) and the recovered frames are tiled into the filmstrip below. A video is just frames + timing - and the frame strip is assembled with an Image-onto-Image Blit (ledger-300 item H, demonstrated). No System.Drawing.

CubeFrames → Gif.Encode → bytes

Gif.Decode → GifFrame[] → Blit each into one strip

encode → decode → recompose: the same frames come back out
