Create a sleek corporate vector illustration on a white background featuring three large stylised waves in sequence, one behind the other, rising diagonally across the composition. The front wave should be the smallest, the middle wave larger, and the back wave the largest. Keep the forms bold, elegant, and highly legible. Use black only for all wave shapes and internal details. No colour. No text. No labels. The waves should feel refined, smooth, graphic, and professionally art directed, with subtle internal linework or contour detail to suggest movement and depth while staying minimal. The overall style should be premium corporate editorial, suitable for a sustainability report or high-end strategy presentation. Clean flat vector design, strong silhouette, elegant spacing, polished composition, modern and sophisticated. Not comic, not cartoon, not hand-drawn, not playful, not decorative, not 3D, not realistic water.
