「Permafrost AUDIO SINGLE NORTHLINE」は FontVibe AI で作成した凍った氷の文字エフェクトです。分厚い氷の塊に閉じ込められた文字。鋭くカットされた氷のファセット、内部まで深く走る霜のひび割れ、そして垂れ下がるつらら。実写のようにリアルな氷結の質感です。

Create a finished square 1:1 single-track cover artwork for the track “Permafrost”. Render only these exact words, with no extra lettering: small eyebrow “AUDIO SINGLE”; dominant headline “Permafrost”; small artist credit “NORTHLINE”. Keep every word correctly spelled and clearly legible. Composition: place “AUDIO SINGLE” near the top edge, centered and small. Center “Permafrost” across the upper-middle, occupying about 78% of the canvas width and 27% of its height. Make it the unmistakable typographic centerpiece. Place the artist credit centered near the bottom edge, separated from the headline. Give the lettering clear negative space and keep all text inside generous cover margins. Build the headline from massive, slightly condensed, sharply angular ice-shard display letters. Use fractured asymmetric pointed stroke endings, thin crack lines inside the strokes, and multiple faceted planes. Each letter is a thick translucent pale blue-white glacial ice block with smooth polished front faces, fine frost micro-crystal bloom around the edges, trapped bright spherical air bubbles, branching internal stress cracks, and a deep cold blue-white glow brightest at its core. Show bright refracted rim-caustic lines and crisp light fans beneath small icicle drips at the letter bases. The artist credit and eyebrow are smaller, clean, widely tracked uppercase lettering with a subtle frost-etched finish, clearly subordinate and legible. The scene includes a distinct arctic subject beneath and behind the title: a fractured glacial ridge and a deep ice fissure, sculpted from translucent blue ice, with layered frozen strata visible through the surface. Set it in a near-black arctic midnight environment with a visible blue-teal aurora borealis glow behind the ridge; do not use a plain black background. Fine airborne ice crystals catch the aurora and the letters’ cold light. Cold blue-white internal illumination, restrained cyan-teal ambient light, high-contrast cold lighting, ray-traced refraction, subsurface scattering through the ice, crisp caustics, detailed 3D render. Zero warm tones. No additional labels, logos, borders, or text.
