Realistic Mechanical Keycaps Render

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