Create a refined horizontal personal identity card, 16:9. Warm-white uncoated document stock fills the frame, subtle natural paper fibers, softly rounded card edges, viewed straight-on with even flat daylight. Center the supplied name "Mahdi" at large scale, spanning 58% of the width. Letter it as a custom founder’s autograph: one continuous, ultrathin blue-black fountain-pen stroke, tall narrow proportions, restrained pressure variation, a gently rising baseline, extended initial M entry stroke, long ascender sweep and a single low underline flourish that ends cleanly beneath the final letter. Keep the signature readable and structurally precise, with tiny natural ink pooling in tight turns and a few faint pen skips in hairline curves; flat matte ink, no metallic sheen, no embossed effect. Below the signature, small spaced uppercase type reads "INDEPENDENT CREATIVE PRACTICE" in crisp dark blue-black, centered. At the lower center, even smaller tracking reads "MAHDI.STUDIO". Leave broad quiet negative space around all text. A slim black fountain pen rests softly out of focus along the far lower-right edge, partly cropped and secondary to the lettering. No logos, no seals, no extra wording, no decorative flourishes beyond the signature’s single underline. Exact text must be rendered verbatim: "Mahdi" / "INDEPENDENT CREATIVE PRACTICE" / "MAHDI.STUDIO".
