Line art, Bauhaus Poster, duotone, god rays, ember sparks. Clean contour outlines form a geometric field of tidal kites arcing and dipping over a harbor, their tethers sweeping in rhythmic grids. Two-colour palette: deep indigo ink and warm sodium-amber. Fanning crepuscular rays slice through hazy air; scattered ember sparks drift upward. Crisp, modernist, awe-filled, purely graphic, no shading.
