新装饰风烛台阶梯菜单边框
八支象牙白烛在黄铜台阶上由低到高排开，整幅图只占左缘，其余留给菜单文字。
✍️ 问题出在透明背景：模型常把棋盘格直接画出来。作者用 alpha = 0、not white、no checkerboard 三层否定堵死，再把中间和右侧划成安全区，菜单才真正能用。

Decorative border artwork, tall 9:16, on a genuinely transparent background (real alpha channel, alpha = 0 at every edge; not white, not tinted, no checkerboard). Everything lives on the left edge: a Neo-Art-Deco candle staircase rising from the lower left to the upper left, made of eight slender bone-white taper candles, each on a small engraved brass step plinth, stepping up in height from the shortest at the base to the tallest at the top so the outline reads as a theatrical stair. A small warm brass teardrop flame tops every wick. The candle bodies alternate deep oxblood and midnight plum with clean bone accents; the plinths are aged brass with fine engraved deco fan and chevron line work over oxblood and midnight plum, plus a restrained simulated metallic-foil sheen. Keep strokes bold and legible, with no hairlines that would disappear. Leave the center and the right two thirds of the frame entirely empty and transparent as a safe area for menu text. The whole graphic floats inside the frame with generous transparent margin all round, touching no edge and cropped by nothing. No text, lettering or numbers anywhere. Flat art-deco illustration: crisp geometric edges, flat color fills, engraved detailing.

9:16竖版装饰边框插画，置于完全透明的背景上：真实的 alpha 通道，每条边缘 alpha = 0，不是白色，不是有色，没有棋盘格图案。新装饰艺术风的烛台阶梯沿左缘由左下向左上攀升：八支纤细的骨白色锥形蜡烛立在刻有纹饰的小型黄铜台阶基座上，高度逐级递增，最矮的在底部、最高的在顶部，构成阶梯式的戏剧性剪影。每根烛芯上一簇暖黄铜色的小水滴形火焰。烛身在深牛血红与午夜梅紫之间交替，点缀清爽的骨白色；基座上是老黄铜色的精细扇形与人字纹装饰线刻，衬在牛血红与午夜梅紫之上，带克制的模拟金属箔光泽。线条粗细足够清晰可辨，没有会消失的发丝线。画面中部与右侧三分之二完全留空，是为菜单文字预留的透明安全区。整个边框图形完整漂浮在画面内部，四周留有充足的透明边距，不触及任何边缘，也不被任何东西裁切。画面中任何位置都没有文字、字母或数字。扁平的装饰艺术插画风格，边缘利落几何，色块平涂，带雕刻细节。
