The tool keeps the title and scrolling message in React state, not persistent storage. You can type your own copy or choose a preset snark line with the random button; the preview immediately uses the current title and message.
Launching the announcement requests fullscreen on the overlay. If the browser denies or lacks fullscreen support, the tool falls back to an in-page overlay state. The marquee animation loops across the screen, and the exit button or fullscreenchange event returns the page to normal.
This tool does not register a result card or encode the title and message into a share link. The fixed share entry can still share the tool URL or QR code, but viewers opening that link start from the default marquee unless you capture the screen yourself.
