摺紙煙花在金銀洋紅間炸開
整朵煙花由硬紙折成，稜面分明，透明底圖直接能拿去疊海報。
✍️ 難點在透明底：只寫“transparent”模型常偷偷畫白底，這裡把 alpha=0、非白、非棋盤格逐項否掉才是變數。邊距和“不裁切”也要明說，不然光芒尖會頂到畫框外。

Square 1:1 frame. A firework burst built entirely from folded paper in gold, silver and magenta: long folded-paper rays fan out from the centre, with small folded-paper stars scattered between them. Every element is creased from stiff paper into angular, origami-like planes with sharp folds and flat tonal facets, all kept inside one coordinated paper palette.
Cut it out on a fully transparent background: alpha = 0 everywhere outside the shapes, never white, never tinted, no checkerboard pattern, a genuine alpha channel. Keep the whole burst well inside the canvas with a clear transparent margin on all four sides, the outer rim completely transparent and nothing clipped by the frame. The artwork floats freely and casts no shadow.

1:1 方形畫幅。一朵完全由摺紙構成的煙花，配色為金、銀、洋紅：長條摺紙光芒從中心向外放射，光芒之間散落著小塊摺紙星星。所有元素都由硬紙折成帶銳利摺痕的稜角平面，色塊平整、分面清晰，統一在同一套紙張配色裡。
以全透明背景摳出：圖形之外 alpha = 0，不是白色、不是有色底、不要棋盤格，必須是真實的 alpha 通道。整朵煙花完整落在畫布內，四周留出透明邊距，最外緣完全透明，不被畫框裁切。作品懸浮，不帶投影。
