/* Orion: the studio site, on the Orion design language v2.1 (D:\Projects\Orion Design\ORION-DESIGN.md).
   Dark only; Rigel-blue accent; colour only when it means something. The glass theme on top is in space.css.
   Motion answers the visitor (hover, scroll, click). The only loops are the product demos and the hero
   diagram, which explain what the products do (§11), and they pause when off-screen or hidden. */
