/* NZXT-ESC FAQ page stylesheet — shared by every generated FAQ locale page
   (dist/faq/index.html, dist/<code>/faq/index.html, ...). Not part of the

   Visual language borrowed from src/styles/root.css + src/styles/config.css:
   dark shell (#1a1c1e) with a centered panel (#121214), DMSans typography,
   purple accent (#a855f7 / #a900ff), squared corners (border-radius: 0
   everywhere except small circular status dots, per project convention). */
