Use case: stylized-concept
Asset type: Seamless geometric repeat tile in RAITEC design for sliding backgrounds.
Output: one square 1:1 texture tile, flat 2D orthographic, requested 2048 x 2048.
Build a rigorously repeating geometric lattice of right-isosceles triangles within a square grid on uniform deep navy #05345d. Thin muted steel-blue #334f76 lines outline triangles, some very subtle blue-gray triangular fills; restrained orange #f7a824 line segments form a tiny fraction of the lattice. The tile is exactly 8 square grid cells wide and 8 cells tall, each cell bisected by the same diagonal; left and right and top and bottom boundaries must have matching periodic phase and matching colors. Shapes that cross an edge re-enter opposite edge at exact same position and angle. Uniform motif density everywhere, no large focus, no bevel, no lighting, no vignette, no gradients. Crisp restrained low-contrast pattern, broad neat geometry; no cube, letters, cross, logo, UI or watermark. Infinite horizontal and vertical repetition without visible boundaries. Avoid diagonal global stripe or arbitrary random elements at boundaries.
