「berserk」は FontVibe AI で作成したバイキングルーンの文字エフェクトです。直線と45度の斜線だけで組んだ角ばったルーン風大文字。オーロラの夜空の下、冷たい鋼灰色の石に彫られています。

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\nberserk centered in bold letters on the stone surface"} Wait, let me re-read the template. The template is just: "flat dark stone surface, cold side light, minimal background, maximum contrast" — there's no existing display text described in it. I need to re-typeset the new text into this minimal template. {"scene":"flat dark stone surface, cold side light, minimal background, maximum contrast. \"berserk\" set in a single centered line of heavy letters, tight tracking, commanding scale against the dark ground."}.
