Styled App Bar - Copy this React, Mui Component to your project

Create a header navigation bar with three centered buttons: 'All', 'About', and 'Work'. The buttons should have a pill shaped design with rounded edges and a transparent background. The active button ('All') should have a subtle outline or glow effect, distinguishing it from the inactive buttons ('About' and 'Work'), which should have a simpler style. The font should be minimalistic and evenly spaced. Ensure the layout is dark themed, with a semi transparent background and a slight gradient, giving it a sleek, modern look.
