/* NGCP documentation, styled as part of ngcpanel.com (the website repo: "NGCPanel Website").
   Light and dark follow the OS (prefers-color-scheme). Works under the site's CSP (default-src 'self'):
   no inline styles or scripts. No inner scroll areas: the page grows, code wraps, tables become cards
   on phones. Fonts load root-absolute from /fonts/ (served by the website); elsewhere the system
   font stack takes over. */
