“二氧化碳”是使用 FontVibe AI 创作的Y2K 泡泡字文字效果。Y2K 泡泡充气字母——圆润柔软的充气造型，粉紫马卡龙配色，糖果光泽表面。甜甜的 2000 年代派对女孩风。

Y2K bubbly inflated letters — extremely round pillow-soft letter forms completely inflated like over-pressurized balloons. Pastel pink-to-lavender gradient across the glossy candy surface. Strong white specular highlight on the top of each inflated letter. Extremely smooth and soft surface. Sweet 2000s Y2K party aesthetic. Maximum bubbly inflation quality. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the over-inflated pillow form, the glossy candy surface and the speculars. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as extremely round over-inflated pillow letters with an ultra-smooth glossy candy surface and a strong white top specular. COLOR PRIORITY: keep the font's own colors if specified; otherwise a pastel pink-to-lavender gradient. Render the exact Chinese text “二氧化碳” as four maximally inflated Y2K candy-plastic balloon glyphs, preserving every stroke and internal negative space with clear readability. Each character has an ultra-smooth pastel pink-to-lavender surface with pearlescent cyan reflections, rounded bulging stroke volume, soft seam-free transitions, and intensely curved pillow geometry at every terminal. Add crisp white oval specular highlights across the upper-facing inflated surfaces, secondary violet reflections along the lower curves, and faint matching inner glow visible at stroke intersections. Surround the characters with translucent bubble spheres, tiny five-point star charms, glossy heart stickers, and miniature molecular-orbit icons rendered in clear acrylic with pink and blue iridescent edges. Use a pale sky-blue, blush-pink, and lavender airbrushed gradient backdrop, with a faint dot-grid pattern, soft floating glitter particles, and subtle white cloud-like haze. Studio lighting uses broad overhead softboxes, ray-traced reflections, soft contact shadows, and high-resolution toy-plastic material detail. Maintain maximum balloon inflation, smooth rounded edges, candy metallic gloss, and clean readable Chinese character silhouettes.
