/*
 * Page chrome shared by the hub's own pages: tokens, layout and the few
 * primitives they have in common.
 *
 * The menu brings its own styles, scoped to `.bk-menu`, and does not read these
 * — so a project with its own design can include the menu without inheriting
 * any of this. This file is only for pages served out of portal/public.
 *
 * Dark mode is chosen, not inverted: each token has its own dark value.
