Title Bar Preview

See exactly how <meta name="document-subtitle"> changes the PWA title bar, taskbar label, and Alt+Tab switcher. Edit the app name, subtitle, and document title, and all three surfaces update live.

document-subtitle: simulated (install as PWA to see real effect)

When installed as a PWA, Chrome 134 builds the window title as: [App name] — [document-subtitle]. Without document-subtitle, it falls back to [App name] — [document.title], which often produces awkward titles like "Gmail — Inbox (47) - Gmail".
