Industrial Matte Black Mechanical Keycap

A high-angle, close-up studio product shot of a single [matte black] mechanical keyboard keycap resting on a clean [white] surface. The keycap is a large rectangular modifier keycap with slightly rounded edges and a subtle fine texture. Deeply engraved into the top center of the keycap is the text "[B.AI]" in a sleek, modern sans-serif typeface. Four small [silver] screws are set into the four corners of the keycap's top face, providing an industrial accent. Soft, diffused studio lighting creates gentle shadows around the base, highlighting its tactile three-dimensional form against the minimalist background.
