I think in the long term, HTML/CSS will win out once there's better support for CSS Paged Module Level 3, and you'll be able to achieve that requirement with just

    @page :left {
        margin-left: 20mm;
        margin-right: 10mm;
    }
    
    @page :right {
        margin-left: 10mm;
        margin-right: 20mm;
    }

instead of needing to install/import different LaTeX packages. I think for most of my current use-cases level 2 has been sufficient but I can see if I can include Paged.js polyfill support by default so there's more support for customizability on that front.

@Page { size: A4; margin: 20mm 10mm 10mm 25mm; } Do my print specifics (hidden-print class etc), everyone can optimize it for his local layout, every browser supports "print to pdf", done.
