sashaga2a24/sentra — reverse-engineered prompt

Build me a polished desktop app called Sentra for managing multiple Roblox accounts in one place. I want a clean modern interface where I can add accounts, see them in an organized list, rename or remove them, and quickly switch between them without digging through files or browser settings.

Please make it feel like a real app, not a rough demo. Use the existing Electron, React, TypeScript setup and keep the design responsive with a simple dashboard style. Treat account data carefully since it can be sensitive, and store user configuration in a predictable local folder, including the Documents/Sentra location on macOS. Include basic empty states, loading states, error messages, and confirmation prompts for destructive actions.

Also wire up the app so it can be packaged for Windows, macOS, and Linux, with automatic update support where the existing project setup allows it. Look up current docs online if you need to.
