/* contoura.ai coming-soon page
   Layout: full-bleed contour field (WebGL: ink on quiet paper, with poché). The text sits on the
   sheet in a title block between two ink rules, bottom left, and the drawing fades out behind it;
   level readout bottom right. Without WebGL (html.no-gl) the text goes back on a Paper box.
