/* AENET Cloud Public — Navigation Fabric v1.1 (subnavigation + system pages).
 *
 * Styles for the registry-driven discovery layer:
 *   - context local navigation (system pages, wallet, domain pages)
 *   - system switcher (searchable, dialog-style)
 *   - Systems directory (compact domain catalog)
 *   - domain pages
 *   - system page header (SYS code / domain / boundary)
 *
 * Design rules (§36–§37): dark raised surface, thin cyan boundary, active
 * cyan accent, domain labels muted, system names high contrast, status
 * secondary, explicit focus-visible — professional platform navigation.
