Jomitm/CRWIStaffManagementSystem ? reverse-engineered prompt

Build me a simple staff management web app for a small company.

I want one clean page where I can add, edit, search, and remove staff records, and see the list update right away. Each staff member should have basic details like name, role, department, contact info, and status, with a simple layout that looks neat on desktop and mobile. Please make it feel like a real usable admin tool, not a demo page.

If it makes sense, add a little offline support too so the app still opens if the connection is weak, and keep the data saved in the browser so it does not disappear on refresh. Use plain JavaScript, HTML, and CSS, and keep the code easy to understand. If you need to check anything current online, feel free to look up the latest docs first.
