/* Document catalogue (templates/core/document_constructor.html).
 *
 * A folder tree: sphere in the rail, a deal per folder, its appendices inside.
 * Namespace is dcl-*, deliberately not dc-*: that belongs to the fill-in page
 * (document-constructor.css), and the two are loaded by different views.
 *
 * Tokens are lifted from style.css so no hex literal repeats down the page,
 * matching what catalogue.css does for the specialists listing. Gold is the
 * site's own --nav-accent, used here only for the folder glyph.
