Description

For very large images, no matter what we do, it will take several seconds to fully analyse all of the layers. nvidia/cuda:13.3.1-cudnn-runtime-ubuntu26.04 is a 2.2 GB-as-.tar image that takes about 15 seconds to load even with multithreading (c.f. #1). I have myself seen images that are over 6 GB in size which will likely be even worse.

This leads to a question about whether we could eagerly show early layer results while waiting for large layers to be processed, since the user will naturally start looking at earlier layers while processing continues, which makes the wait more bearable.

Research direction

Start by reading issue #1 and tracing how image layers are parsed before the UI is shown. Determine where parsing completion gates the initial display and define the behavior for showing early layer results while later layers continue processing. Done means large images display usable early results before all layers finish.
