Export format: "png"

[WillsterJohnson]

Using the canvas npm package and the built-in node:fs module, we can write the result of a "prime" export to a virtual HTMLCanvasElement and then pipe that canvas to a file.
The file size will be proportional to the configured --width, the most likely solution is a multiplier that decreases through some function as a the configured --width increases, approaching a multiplier of 1.
