/* Darkride Chat: the website's look (vr.darkride.ai), so that the chat reads as the same site. The palette is

   "Digital Night": a mid-dark page, lighter cards, soft white text, the logo's cyan d and violet R). Roboto, as
   the site, from assets/ (assets/README.md).
   Written for Chromium 83 (no :has, no aspect-ratio, no container queries, no inset) so the viewer's page
   engine draws it as a browser does. Flex gap needs 84: on 83 items only sit closer. */
