这套叶子差分，边缘严丝合缝

Build a seamless surface pattern out of simplified palm leaves, banana leaves, and a scattering of small fern accents, each rendered as a clean flat shape. Blend dusky blue, cream, and muted terracotta into the palette for a subtly contemporary feel. Let the leaves overlap lightly while their contour lines stay crisp and clean. Across every edge, the repeat should align perfectly, producing an uninterrupted flow with no visible break. Hold the whole design to a strict vector aesthetic - no added texture, no shading.

做一整片可无缝重复的表面图案，由简化的棕榈叶、香蕉叶和零星的蕨类点缀组成，每一片都是干净利落的平面形状。配色调入灰蓝、奶油白与低饱和赤陶色，透出一种低调的现代感。叶片之间轻轻叠压，但轮廓线始终保持干净清晰。任意边缘拼接都要完全对齐，形成没有断点的连续流动感。整体严格保持矢量美学——不加纹理，不加阴影。
