“20% OFF”是使用 FontVibe AI 创作的玻璃文字效果。透明光学玻璃大写字母折射光线，边缘高光明亮并带焦散，倒映在深色台面上，背景是青绿色极光夜空。

High-clarity optical-glass letterforms with lightly frosted surface diffusion, visible light transmission through the glyph bodies, deep internal optical depth, and intense refraction. Preserve the supplied letterform shapes as the primary visual structure; apply the glass treatment to their existing contours. Render transparent clear glass with no color tint, no opacity, no metallic coating, and no fully opaque fills. Sharp bright specular highlights trace thickness transitions, beveled edges, curves, counters, and terminals. Slight organic liquid-pulled surface tension subtly softens terminals and curved joins. Dense bright caustic refractions cling directly beneath the letter edges as physically projected optical light. Maintain frosted diffusion while retaining transparent internal transmission and refractive detail. Centered two-line promotional lettering reading “20%” above “OFF”, with “20%” massive and dominant, spanning approximately 65% of the frame width, and “OFF” beneath at approximately 22% width in refined small caps. The glyphs are sculpted from high-clarity optical glass with a lightly frosted diffusion across the outer surfaces, retaining visible internal light transmission, deep optical thickness, and refracted distortions within every stroke. Bright white edge highlights precisely trace bevel transitions, counters, curves, and the percent symbol. Subtle liquid-pulled surface tension rounds the terminals and inner corners without changing the supplied letter shapes. Dense white caustic patterns are physically cast immediately beneath the lower edges of each glyph, attached closely to the lettering as luminous refracted light. Use crisp centered alignment, controlled vertical spacing, and a clean hierarchy with no added ornaments, objects, or text. The background is a perfectly flat pure BLACK #000000 void with nothing else.
