/* PROCESS, art-directed version (mockup).
   Direction: a world first should be seen, not described. The page lets the visitor watch a digital painting become an object,
   follow one painting through its three states, then hold the light themselves and move it across the sculpted surface.
   The demonstration chapters are always dark (a studio with the lights down); the reading passages follow the site theme. */
