/* MetropolitanHost Studio builder — full new UI shell.
 * Wraps the legacy sectionize-main shell with a global sidebar (248px),
 * topbar (56px), and a 3-column main area: generation panel · canvas · project panel.
 *
 * Loaded after assets/css/main.css (legacy) and tokens.css (new).
 *
 * Architecture:
 *   .studio-app                              <- outer grid (sidebar | (topbar above main))
 *     .studio-sb                             <- GLOBAL nav, app-wide (Dashboard, Builder…)
 *     .studio-tb                             <- topbar (breadcrumbs, save, publish…)
 *     .studio-main-area                      <- holds the 3-col workspace
 *       .studio_app-shell  (legacy)            <- left panel + canvas + right drawer
 *
 * The left panel is the GENERATION OPTIONS surface (One Page, RTL, DNA, Style,
 * Template size). It is intentionally distinct from the global sidebar.
