23/// Create an isolated CEF RequestContext for a new browser window.
24///
25/// Each browser window needs its own renderer process to get an isolated
26/// JavaScript context (own `document`, own module state, own SolidJS render tree).
27/// CEF assigns a separate renderer process when the RequestContext has a unique
28/// `cache_path`. We use `<data_dir>/browser-contexts/<label>/` for this.
