• CADR and Genera interface style guide provides a source- and runtime-grounded Genera visual profile, contrasts it with CADR without averaging the systems, and links the public Genera 8.5 font reproduction and its publication boundary.
• Software areas, applications, and programs in the inspected Genera 8.5 environment catalogs the live activity, Select-key, System Menu, and command-area registries; all 98 live loaded-system names; the base release roster; all 133 site/system-directory identifiers; optional products, services, language tools, and registered demonstrations, while keeping runtime, documentation, and media-presence claims distinct.
• How CLIM was used across the CADR and Genera software catalogs classifies every canonical dossier by its real UI substrate and distinguishes CLIM applications, ports, integrations, and compatibility hooks from native Dynamic Windows, ZWEI, TV, and noninteractive facilities.
