「CASTANYADA」は FontVibe AI で作成した血のしたたるフォントの文字エフェクトです。濡れた暗赤色の表面を持つ太い深紅の文字。長い血の滴は丸い粒で終わり、横からの光を受けて真っ黒な背景に浮かびます。

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). Square composition, “CASTANYADA” as the sole dominant text, centered with generous breathing room around the full word. Deep, nearly black background with a cold charcoal-brown undertone; no warm autumn scenery or colorful decoration. Treat every letter as thick, viscous crimson blood, with realistic glossy surfaces and heavy gravity-driven drips. Blood shifts from arterial red along illuminated ridges to dark maroon and near-black in recessed areas and pooled shadows. Several broad drips descend from the letter bottoms, wide where they cling to the forms and narrowing into rounded teardrop terminals; smaller suspended drops show taut surface tension. Subtle dark pooling gathers beneath the lettering without obscuring any character. A narrow, cold side light grazes from the left, catching wet highlights and revealing the thickness of the blood while the opposite edges fall into dense shadow. Faint red subsurface glow shows through the thinnest hanging streams. Keep the word crisp, unmistakable, and fully legible, with restrained splatter confined close to the letters. Visceral practical-horror atmosphere, stark black negative space, no extra words or symbols.
