The documentation reserves three 16:9 slots:

Filename Capture
main-window.png Main workflow after selecting an image, with both readiness cards and output controls visible
build-progress.png Progress window showing status, split progress pill, colored logs, and diagnostic controls
maintainer-workspace.png Permission-gated maintainer window with a validated plan and local editor target

Capture at native scale, crop to 16:9, keep the application window sharp, apply a restrained Gaussian blur to unrelated desktop content, and redact host usernames, paths, device serials, tokens, and credentials. Prefer PNG and keep each image below 2 MiB. The *-readme.png variants are tighter 16:9 crops for the two-column repository landing page.
