/* desk.css — the Workspace shell (the installable app at /app/; controller: js/desk.js).
   The sidebar is a fixed dark rail (the Caspian house palette); the content pane follows the
   app's own light/dark tokens so every tool renders exactly as it does on the site. Every class
   is prefixed dk-. The site's own chrome (header, mega-menu, footer, help block) is hidden, never
   removed, so app.js keeps every element it expects. Loaded only by /app/index.html. */
