Spell Card

Spell card 0.063 x 0.088 m and 0.0005 m thick: a parchment face inside a 1.5x gold frame, a coloured school banner across the top, a faceted rune roundel, the body as printed text lines, a dark green patterned back; school knob red, blue, green, violet.

风格：low-poly, flat-shaded vertex colors, no textures, 3 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
