Is there an external package that can implement more complex animations for slides from Touying or Polylux?

Typstage has some animation features – not sure if the kind you need, but still:

Typstage: animated HTML presentations from a single Typst file

[image-1788000150915] Slides in Typst tend to end one of two ways. The PDF route gives you one page per step and nothing ever moves. Typst’s own HTML export hands the arrangement to the browser, which loses the very thing I use Typst for. I tried a third route, and a package came out of it. Every slide is typeset by Typst and written into the HTML as SVG. What you see in the browser is Typst’s layout, to the point, the same one the PDF shows. Only then does anything move: whatever should…

it definitely targets HTML, so bundling efforts could make sense
