The HTML, ECMAScript, and even #Pandoc and Lua fold together with Phil Harvey's #ExifTool. This particular hack is a filter that calculates the sizes of a #latex wrapfigure command, using a #deno backend running #LocalFirst that generates a 1.4MB single page HTML web app rendering of 1300 articles w/ included libraries as well as a PDF. Deno=ubiquitous compute: cloud upside down. (I can't keep #JoniMitchell from singing her song in my head, but it is true... I've seen both sides now.)
