   Nonlinear Platform — platform page visuals (v2.1.0)
   Hero artwork, application screenshots, charts and "at a glance" tables
   of the natively written platform pages (inc/platform-visuals.php).
   Every chart is readable without JavaScript; the entrance animations
   only run when the page has the nlp-js class and the chart is reached.
