“NUADA”是使用 FontVibe AI 创作的维京卢恩文字效果。只用直线和 45 度斜线构成的棱角符文风大写字母，刻在冷钢灰色的石头上，头顶是极光夜空。

Elder Futhark runic letterforms — straight strokes only at horizontal, vertical, and 45-degree angles. Tall narrow proportions, sharp pointed terminals, strong vertical stave emphasis. Clean angular geometry — each letter reads as a precise geometric skeleton carved with a straight blade. Powerfully minimal. {"scene":"flat dark stone surface, cold side light, minimal background, maximum contrast\n\nNUADA centered in massive bold letters spanning the full width."} Wait, I need to re-read the template. The template is just: "flat dark stone surface, cold side light, minimal background, maximum contrast" — there's no display text or layout described in it. Let me provide the proper output. {"scene":"flat dark stone surface, cold side light, minimal background, maximum contrast\n\nNUADA centered in large bold letters on the stone surface."} Hmm, I should just return clean JSON. Let me reconsider — the template has no old display text, so I incorporate the new text into a layout that fits the template's style. {"scene":"NUADA centered in large bold letters. Flat dark stone surface, cold side light, minimal background, maximum contrast."}.
