// Example H — viewer mode: SWViewerHeader (data-driven menu) + SWViewerPanel popups with free content.
// Only public components. The program owns the state and the commands; the package owns the look and the
// open / close / focus / keyboard / drag behavior. Icons are the program's own (16px, currentColor).
