“Design a vertical wallpaper reading Slow Down with glass panes”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。

Vertical 9:16 phone wallpaper, text-driven composition. Render the exact headline “Slow Down” in two centered lines, “Slow” above “Down”, occupying the middle 55% of the canvas. Custom display lettering built as thick, softly rounded crystal-glass characters: precise monoline strokes, generous counters, wide calm spacing, smooth circular curves, lightly softened terminals; each letter is cast from fully transparent clear optical glass, not opaque. Show subtle refractive distortion of the background through the letter bodies, parallel cut-glass facets along sidewalls, thin white specular contours at thickness transitions, tiny prismatic rainbow dispersion only on sharp edge angles, and concentrated caustic highlights within curved counters. Construct the background from six oversized vertical and horizontal clear-glass window panes with slim transparent seams, arranged as an offset architectural grid. Panes fill the full canvas; their boundaries pass behind, never through, the headline’s readable silhouette. Behind them: a pale lavender-to-cool-blue daylight gradient, #DCD7FF at top blending into #BFCFF5 and nearly white #F5F7FF at bottom. The panes create softly blurred refraction, faint double reflections, and delicate caustic pools directly below the headline. Gentle diffused backlight passes through the panes; a narrow upper-left key light produces controlled bright edge glints, with no dark shadows, no objects, no people, no extra wording. Clean generous negative space, crisp centered alignment, premium optical-product render, ray-traced transparent refraction, high-resolution vertical lock-screen crop.
