/* =====================================================================
   help.css: loaded after the cabinet's own /core/css/core.css and /core/css/fa.css (common/header.php).
   Every class here starts with help-. The rest of the markup uses core.css classes the way the cabinet does:
   main-header, logo, sidebar-toggle, main-sidebar, sidebar-menu, treeview-menu, content-wrapper, content-header,
   breadcrumb, section-label, table, btn, label, modal, main-footer, fa.
   Colours, radii, shadows and control heights come only from core.css tokens
   (--c-*, --accent*, --header-*, --sidebar-*, --radius*, --shadow-*, --h-*).
   No hue literal and no prefers-color-scheme block: light/dark and the colour scheme (body.skin-*) arrive through
   the tokens. The one colour value is the neutral black backdrop of an enlarged screenshot, rgba(0,0,0,...), as in
   core.css. Breakpoints are core's: 767 / 991 / 1199. Design: docs/design/ui.md.
