从森林到洞穴的横版卷轴地图

Create a wide horizontal 2D side-scrolling beat-em-up game background map showing a seamless transition from an enchanted forest into a dark cave. Use a very wide panoramic canvas in a {argument name="aspect ratio" default="24:5"} ratio, with no characters, no UI, and no text. The scene is a hand-painted fantasy environment with muted earthy greens, browns, ochres, and soft dusty lighting, like an old watercolor or pixel-art-inspired game stage backdrop. The foreground is a straight flat walkway made of exactly 9 large decorative stone tiles stretching across the bottom third of the image; each tile has an oval medallion containing a stylized leaf or flower motif, separated by thin grout lines, with a narrow grass strip along the very bottom edge. On the left half, show a dense forest: tall thin tree trunks repeating in vertical rows, a mossy leafy canopy hanging down from the top, vines and undergrowth at the base, and atmospheric depth fading into green shadow. At the center-right, place one massive ancient tree trunk acting as the natural transition boundary; its roots and bark merge into the cave entrance. On the right half, show a dim cavern interior with dark rock walls, stalactites hanging from the ceiling, stalagmites rising from the floor, and deep shadow fading toward black, while still aligning perfectly with the same flat walkway. Make the composition side-view and game-ready, with clean horizontal layering, parallax-friendly depth, soft vignette at the edges, and a continuous navigable floor from forest to cave. Visual style: {argument name="visual style" default="hand-painted 2D fantasy game background"}, mood: {argument name="mood" default="quiet mysterious forest-to-cave transition"}, color palette: {argument name="color palette" default="muted moss green, sepia brown, dark charcoal cave shadows, pale stone"}.

创建一张宽幅水平 2D 横版卷轴清版动作游戏背景地图，展示从魔法森林到黑暗洞穴的无缝过渡。使用超宽全景画布，比例为 {argument name="aspect ratio" default="24:5"}，画面中不包含角色、UI 或文字。场景为手绘奇幻风格，采用柔和的土绿色、棕色、赭色以及朦胧的尘埃光影，呈现出类似水彩画或像素艺术风格的游戏关卡背景。前景是一条平坦的直走道，由 9 块大型装饰性石砖铺设而成，横跨图像底部三分之一处；每块石砖上都有一个椭圆形徽章，内含风格化的叶片或花卉图案，砖块间有细小的缝隙，最底边缘有一条狭窄的草地。左半部分展示茂密的森林：垂直排列的高瘦树干、从顶部垂下的苔藓叶冠、底部的藤蔓和灌木丛，以及逐渐淡入绿色阴影的氛围感深度。在中心偏右处，放置一棵巨大的古树树干作为自然的过渡边界；其根部和树皮与洞穴入口融为一体。右半部分展示昏暗的洞穴内部，包括深色的岩壁、从天花板垂下的钟乳石、从地面升起的石笋，以及向黑色渐变的深邃阴影，同时与底部的平坦走道完美对齐。构图采用侧视图，适合游戏使用，具有清晰的水平分层、适合视差滚动的深度、边缘柔和的暗角，以及从森林到洞穴连续且可通行的地面。视觉风格：{argument name="visual style" default="手绘 2D 奇幻游戏背景"}，氛围：{argument name="mood" default="宁静神秘的森林到洞穴过渡"}，调色板：{argument name="color palette" default="柔和的苔藓绿、深褐色、深炭色洞穴阴影、浅色石材"}。
