4th VM e2e: kiosk shell engages + the app launches fullscreen, but the Blazor wizard renders BLANK and the kiosk chrome didn't apply (title bar present) — the app didn't crash, so there's no log to read. Two changes: 1) ApplyKioskChrome made defensive (null-guard HWND/AppWindow, FullScreen presenter only, returns bool) and wrapped in try/catch at the call site, so a chrome failure can never stall app/WebView startup (the likely cause of the blank). 2) Always-on file log at C:\ProgramData\SilverMetal\welcome.log: app ctor, window create, chrome result, unhandled exceptions, and the BlazorWebView/WebView2 lifecycle (Initialized, NavigationCompleted, ProcessFailed). If the wizard is still blank next run, this pinpoints whether WebView2 env creation failed. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
