“病毒样本位置” es un efecto de texto Letras de Sangre creado con FontVibe IA. Letras carmesí gruesas con una superficie roja oscura y húmeda y largos goteos de sangre que terminan en gotas redondas, aisladas sobre negro puro con luz lateral.

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). Portrait 3:4 composition. Render the exact text “病毒样本位置” as the sole dominant centered title, arranged in two balanced lines with stark negative space around it. Pure black laboratory void behind the text, with only the faintest suggestion of a cold stainless evidence tray disappearing into darkness at the lower edge. Every character is saturated in thick biological crimson: active arterial-red fluid along the upper planes grading into deep near-black clotted pools at the lower edges. Heavy gravity-pulled drips descend from the character bases, broad where they emerge, narrowing into uneven connecting streams and ending in large suspended tear-shaped drops with visible surface tension. Fresh convex drops carry sharp cold-white side highlights; recessed clot zones remain matte, brown-black, and dense. A few tiny blood micro-droplets hover close to the longest drips, never decorating the empty field. Low blue-gray side light from the left exposes wet gloss and a faint deep-red subsurface glow, while the right side falls into black. At the bottom, restrained dark blood pooling merges with shadow. Clinical containment dread, photorealistic horror practical-effects finish, no warm colors, no extra words.
