“博愛”是使用 FontVibe AI 创作的血滴字体文字效果。粗体深红字母，表面湿润暗红，长长的血滴末端凝成圆珠，在侧光下孤立于纯黑背景。

Thick crimson blood saturating every surface — viscous, high-density fluid with authentic physical behavior: large tear-shaped drops suspended at each drip terminus with surface tension visible at the meniscus, connecting streams thinning as they extend downward, deep near-black pooling where blood accumulates. Material properties: subsurface scattering gives deep red glow when backlit, specular gloss on convex drip surfaces catching directional light, matte-dark at clotted pooling zones. Blood color gradient from bright arterial red (#CC0000) at active drip streams to near-black clot (#3D0000) at base pools. Gravity-driven physics — every drip pulled downward with anatomically accurate tension. Horror film practical effects quality — not painted, not stylized, photorealistic blood. 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 viscous blood fluid physics, the suspended drips and the pooling. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as viscous crimson blood letters with tear-shaped drops held by surface tension, thinning connecting streams and near-black pooling. COLOR PRIORITY: keep the font's own colors if specified; otherwise arterial red (#CC0000) grading to near-black clot (#3D0000). The rendered text “博愛” dominates a deep pure-black void, its existing letterform contours fully preserved beneath a dense coating of viscous arterial blood. Every lower edge releases gravity-pulled crimson streams: broad wet sources narrowing into elongated connecting filaments, each ending in heavy tear-shaped drops held by visible surface tension. Fresh active liquid carries bright arterial red (#CC0000) along convex surfaces, while recessed seams, accumulated edges, and thick pools shift into coagulated near-black maroon (#3D0000). Photorealistic practical-effects blood material, with ray-traced specular highlights tracing the curved drop menisci, subtle subsurface red glow where cold side light passes through thinner liquid, and matte clotted crust at the densest deposits. A few tiny satellite droplets hover near the longest streams, formed by realistic fluid separation rather than decorative splatter. The black ground beneath catches shallow, irregular blood pools with almost-black outer rims and wet crimson reflections. Cold, low-intensity directional light from one side isolates the liquid relief against the darkness; the opposite surfaces dissolve into dense black shadow. No warm background tones, no props, no colorful elements, no paint texture: heavy biological fluid, thick slow drips, sharp wet detail, high-resolution horror-film practical makeup photography.
