mallajyothiprakash/rectorplus ? reverse-engineered prompt

Build me a simple Android app called RectorPlus with a clean modern feel. I want it to open to a straightforward home screen, let the user see the main content right away, and make it easy to tap around without feeling cluttered. Keep the design polished, responsive, and mobile friendly, with a nice light and dark look if that’s easy to add.

Use the existing project setup and wire up anything needed so it runs cleanly in Android Studio. If you need to check current best practices or docs for anything small, go ahead and look them up online. I mainly want a solid working starter app that feels finished, not a toy demo. Please include sensible placeholder content and make sure the app builds and launches without errors.
