Build me a dark themed Death Note inspired web app that feels spooky and cinematic.

I want a simple single page experience where someone can type a name, add a reason, and save it into a dramatic looking notebook style list. Make it feel like an interactive fan project, with a black and red visual style, subtle animations, and a clean mobile friendly layout. It should have a top area for entering a new entry, a place to view saved entries, and buttons to add, clear, and delete items.

Keep it polished and fun, with strong typography and a little atmosphere, but still easy to use. If it helps, make the app work as a front end only project with local saved data so entries stay after refresh. Please make the UI feel complete and ready to show off, and look up current docs online if you need to.
