Goal: Create a serene Zen minimalist diptych poster combining cinematic nature photography with sparse ink illustration, themed around {argument name="quote" default="stillness is a return."}

Canvas: Vertical 3:4 poster, split horizontally into exactly 2 equal-feeling sections. The upper half is a moody photographic lake scene; the lower half is an off-white minimalist illustration field. No border, no watermark.

Upper panel: A lone meditating figure sits centered on a tiny bamboo raft in the middle of a dark teal lake, facing away from the viewer. The figure wears a deep indigo robe and a pale conical straw hat, seated cross-legged. The water is calm with subtle ripples and a soft vertical reflection of the person and hat below the raft. In the background, show a dense dark green forest across the lake and one pale vertical limestone cliff partly visible near the upper center-left, softly out of focus. Use cool blue-green grading, high stillness, atmospheric depth, symmetrical calm composition, lots of negative space around the subject.

Lower panel: Use warm ivory paper texture. Place a small black stippled ink illustration of the same meditating figure and bamboo raft slightly below center, aligned with the subject above. The illustration contains exactly 1 seated figure, 1 conical hat, 1 raft, and 1 soft vertical water reflection made of dotted halftone marks and thin broken horizontal lines. Keep it monochrome black ink with sparse texture.

Text and mark: In the lower panel, place the quote in small thin serif lowercase type near the upper-right area, broken into exactly 4 stacked lines: “stillness” / “is” / “a” / “return.” Place exactly 1 small solid black dot below and slightly left of the text block. Do not add any other text.

Visual style: Chinese Zen aesthetic, minimal editorial poster design, quiet negative space, refined asymmetry, meditative mood, soft film photography on top, delicate pointillist ink drawing below. Use {argument name="upper panel color mood" default="deep teal and forest green"}, {argument name="robe color" default="deep indigo"}, and {argument name="paper color" default="warm ivory"}.
