SefEpanya/restau-web-manager ? reverse-engineered prompt

Build me a simple web app for restaurant managers so they can keep track of day to day operations in one place.

I want a clean dashboard where a manager can see the most important stuff at a glance, like orders, table status, menu items, staff activity, and basic sales info. It should be easy to add, edit, and remove restaurant data, and the interface should feel modern and straightforward for someone who is busy and not very technical.

Please make it responsive so it works well on desktop and tablet, and keep the flow simple with clear navigation. If you need to look up current best practices or docs while building it, feel free to do that. Focus on something practical and polished that a restaurant manager could actually use every day.
