提示詞

Detailed botanical-realism close-up of ancient cedar roots arching over a winding water channel in a fern-covered temperate rainforest ravine, viewed from a low angle. Deep umber bark, emerald ferns and moss, and subtle amber highlights; soft shafts of filtered afternoon light illuminate the sheltered, timeless scene. Controlled visual noise, natural textures, no text, watermark, logo, border, UI, or interface elements.
