Create a clean, black-and-white stencil design in the style of simple SVG line art. It should be a symmetrical tribal emblem with thick, solid-black shapes. At the center, include a bold keyhole/lock symbol (round top, tapered rectangular bottom). Surround the keyhole with symmetrical, sharp, angular tribal lines: two upward-pointing horn-like arcs and two downward-pointing arcs forming an abstract heart-like structure. Two extra wider arcs pointing to each side. No shading, no gradients, only solid black on white. Make it clean, crisp, and stencil-ready for tattoo transfer. See more
