3D Mechanical Keycap Render

A highly realistic 3D render shows four mechanical keyboard keycaps arranged in a tightly arranged 2x2 grid, with all keycaps touching each other. Observed from an isometric angle. One keycap is transparent, printed in red with the words "{just}". The other three keycaps come in colors: {black, purple, and white}. One keycap features the Github logo. The other two keycaps are labeled "{fork}" and "{it}" respectively. Realistic plastic texture, rounded engraved keycaps, soft shadows, and a clean light gray background.
