Overwrite it only when the user explicitly asked to refresh, replace, remake, or restyle it; otherwise report the existing asset and stop. 5.

Check for unrelated stale sources before running it; stop and report a scope conflict if the command would regenerate another article's WebP. ## Read the sources of truth Read the target English article fully.
