Overview

What ActiveStorage::Previewer::PopplerPDFPreviewer does, moved out of the application: the Poppler sibling of the mutool preview, for an image whose Rails default previewer chain reaches pdftoppm first.

Rails runs pdftoppm -singlefile -cropbox -r 72 -png <file> and streams the result through the web process. This reads the input through its descriptor and writes to the worker's own scratch.
