日式禪意水墨畫，描繪茶杯與竹枝，意境悠遠

提示詞

Create a minimalist zen-style Japanese ink wash illustration on a vertical canvas. Use warm aged rice paper as the background with subtle beige watercolor stains and abundant negative space. Place a single rustic ceramic tea cup in the lower-right area, rounded and slightly imperfect, with speckled beige clay texture, a thin dark rim, a visible amber-brown tea surface, and a soft gray ink shadow beneath it. From the cup, draw one graceful column of steam made of thin, translucent, flowing S-shaped black-gray brush lines rising upward. On the left side, include one slender bamboo branch entering diagonally from the lower-left edge and reaching toward the upper-left and center, with exactly 3 visible stem segments and exactly 12 narrow bamboo leaves in muted black, charcoal, and pale gray ink tones. Add 2 small ink dots near the lower-left of the cup. Keep the composition quiet, asymmetrical, meditative, and elegant, with soft organic brush textures, sumi-e linework, light watercolor washes, no hard outlines except the expressive ink strokes, no text, no border, no watermark.
