Eastern Ink Wash Poster Design

Design a visual poster with the style of Eastern ink wash animation for [{argument name="theme" default="Borrowing Arrows with Straw Boats"}]. The overall visual logic adopts the principle of 'heavy ink to establish structure, light color to create a scene, blank narrative, and edge breathing.' The background features a warm Xuan paper texture, naturally blended with off-white, light blue-gray, and freshwater colors, with slight paper grain, water marks, and ink diffusion.

The core text in the picture is not fixed in a single position, but is intelligently arranged based on the subject's actions, gaze direction, blank space, and visual focus. Titles can appear on the left, right, above, below, diagonally, with semi-exposed edges, or arranged in a staggered manner around the main body. The text should be positioned like a natural part of the image, not just pasted in post-production layout.

The main title serves as a visual anchor in the dense ink and participates in the composition, serving to hold the image, support the main subject, guide the gaze, or create rhythm. The title font is handwritten in heavy ink calligraphy, with thick, moist, childish, irregular strokes, featuring flying white, broken strokes, ink clumps, soaking, and rough edges. The sizes of the characters are staggered, with a slight shifting center of gravity, evoking the handmade feel of children's picture books and Chinese ink animation openings. The title should not use a neat commercial font but should resemble a set of black graphic symbols that echo the main body, edge elements, and blank space.

Keep a moderate amount of blank space in the center of the image, letting the main characters or core objects gently fall into the air on the paper. Incorporate pale edge elements around the perimeter that change according to the theme, such as [{argument name="Edge Element" default="Willow Branch, Water Flower"}]. These elements extend from outside the frame, only partially revealing and not fully displayed. Edges use ink pale coloring, transparent grading, and local blur treatments to create an external space and a sense of breathability. Color mainly appears at the edges and corners, with the central area kept clean and restrained.

The overall vibe is poetic, childlike, Eastern, gentle, and hand-drawn, like a breathing Chinese ink animation poster. The composition should have a sophisticated design sense of "heavy ink text as the framework, light color edges as atmosphere, and blank spaces telling the story."
