/* qxavier v1. the page is ordinary html first. when the grain engine runs, the marked parts of it (data-gt text, data-gf frames, data-gr rules)
   are drawn as matter instead, and the real text stays in place, transparent, so it can still be read aloud, selected, searched and tabbed through.
   plain mode (or no webgl, or no script) shows this same page as it is here. */
