Create a finished email-footer signature graphic, wide horizontal 16:9 composition. Render only the exact name “David Okafor” as a genuinely hand-signed autograph, not typeset lettering. Use one confident fluid pen pass: a dominant oversized capital D with a sweeping entry stroke, clearly legible connected letters in lively forward slant, firm downstrokes tapering into lighter joins, then a bold underline swash sweeping beneath the full name. Keep the signature distinctive and fully readable at small email-footer display size. Use a single flat deep blue-black matte fountain-pen ink, subtle natural pooling at turns and faint skips at lifted joins; no gloss, metallic finish, decorative flourishes beyond the authentic signature strokes, or extra wording. Place it centered on a plain warm-white uncoated card-stock signing surface with generous clean negative space. Even soft daylight, minimal shadows, document-like clarity, crisp edges, restrained paper grain, high-resolution scan-like finish. No pen, hands, desk objects, border, logo, or watermark.
