「DF」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。

rendered in Elder Futhark runic letterforms — all strokes constructed from straight segments at horizontal, vertical, and 45-degree diagonal angles only; no curves anywhere, angular geometry derived from the physical constraint of carving into stone with a straight blade. Tall narrow proportions, strong vertical emphasis, sharp pointed terminals where strokes meet. Each stroke presents a flat angular face — illuminated and shadow faces alternate across the word creating the faceted highlight pattern of hand-carved letters. Pure runic geometry, powerfully ancient. Two-character runic monogram 'DF' in massive Elder Futhark letterforms, each glyph constructed from pure straight-segment strokes — vertical spines, horizontal cross-bars, 45-degree diagonal branches — zero curves, absolute angular precision. Letters fill the frame with maximum geometric density, tall narrow proportions, sharp pointed terminals. Flat angular stroke faces catch a single cold key light from upper-left, alternating illuminated and shadow faces creating deep faceted contrast across each letterform. Background: pure obsidian-black field, borderless darkness. Cold blue-white rim light traces the outer silhouette of each letter, electroluminescent edge quality, razor-thin. Floor plane: polished black anodized surface reflecting faint ghost-images of the letter bases. No particles, no fire, no organic texture. Minimal esports logo register — two glyphs as pure typographic icon, tournament-stage authority, clean geometric statement against void. Ultra-high-contrast, octane render quality, 8k sharpness.
