Create a highly detailed, engraving-ready black-and-white vector illustration of Santa Claus. He should have a warm smiling face, a classic fluffy beard, and a richly textured hat. Add deep, realistic shading (engraving style cross-hatching) with smooth gradients made from fine vector lines. Santa is carrying a large gift bag over his shoulder, with visible folds, shadows, and subtle texture. The entire artwork must be clean, high-contrast, optimized for laser engraving, with no grey fills — only black vector lines and shading patterns. The final result should look like a masterful vintage engraving, crisp, elegant, and ready for LightBurn.
