Make “Paper-Cut Botanical Vessel Poster Design” yours

Generate a bright, clean, flat poster-style image built around a specific theme. First turn the theme's core keyword into a single line of extremely bold sans-serif giant letters, letting the letterforms create a huge structural backdrop across the upper part of the image; the letter faces carry a slight paper grain and semi-transparent printing texture, are naturally cropped by the frame edges, and act only as a clear visual wall without overly stealing the subject. Place the subject near the central axis, using a childlike handmade paper-cut line-drawn vessel to hold the theme's symbolic object: the vessel is shown as a single-line contour, its rim and base formed by oval lines creating transparent space, with a few slender straight rods, blunt rounded leaves, and simplified block flower shapes emerging from inside, shaped like layered cut paper, with clean, geometric edges and slight handmade deviation. Keep the information layer sparse, scattering small month, number, or theme-node text on both sides of the subject in rounded bold type, with colors echoing the corresponding small shapes; below, keep two short paragraph blocks and a tiny signature-style footer, with tight but still legible letter and line spacing, forming the reading rhythm of a playful infographic. Draw the colors from the theme's own season, material, and mood: the background carries a large-area high-brightness clean base field, the main title uses a bright structural color of variable warmth, the subject's branches or skeleton use a clear highly saturated support color, the flowers or symbolic blocks use a small amount of bright accent color, and the small text is allotted from these accent colors; overall it stays bright and light with a strong airy feel, clear tonal steps, saturated but not muddy, with the paper grain providing only a soft tactile touch without creating an aged look. The image's focus is the scale contrast between the oversized typographic backdrop and the central line-drawn vessel, and the light order among the childlike shapes, empty space, and small informational text.
