You can make any document into a full blown web page. I remember looking at the source of a snappy yet functional web page recently. It was the raw XML output from their code comments with an XML front page. It was all just raw XML and CSS. There is no "time until valid paint". Everything renders when it's done, which means you get a lag before things show up in screen where you otherwise already have things rendering.
