Pattern / Textile / Wallpaper Design (图案纹样)

Seamless repeating pattern design: {{motif: hand-drawn mushrooms and ferns}}, {{color palette: sage, terracotta, cream}}, scattered in balanced non-grid rhythm, flat gouache illustration with paper texture, even visual weight across the frame so edges tile invisibly, no borders, no text, repeat pattern ready for fabric/wallpaper, vintage naturalist sketchbook aesthetic --ar 1:1 --style raw (Tip: 出图后在 SD 用 "tile" / Photoshop offset 接缝检查。)
