「GRID」は FontVibe AI で作成したジオメトリックの文字エフェクトです。円、四角、直線で組み立てたバウハウス風の大文字。赤・青・黄・黒のベタ塗りで、硬いトップライトの下に積み木のように立ちます。

Bauhaus geometric environment: hard overhead directional light — single cold-white source, zero ambient scatter, ruler-sharp geometric shadow edges below all forms. Background plane is architecturally flat: pure black void, deep matte concrete, or stark white plaster. No depth haze, no organic texture, no atmospheric bokeh. Scene vocabulary: Bauhaus workshop geometry, De Stijl primary-color planes, Constructivist poster surface, Swiss grid precision. Primary color atmosphere (always active): flat geometric primary-color planes — signal red, cobalt blue, cadmium yellow — appear as background architectural blocks or compositional color bars alongside the letterforms. Zero gradient, zero sheen. When no specific material is defined by the font: letterforms rendered with Bauhaus primary color flat-paint treatment — each letter one vivid matte hue cycling across the primary palette: signal red, cobalt blue, cadmium yellow, flat black. Hard 45-degree isometric extrusion with pure-black side wall, depth 25% of letter height. Flat matte acrylic surface, zero sheen. Sharp machined edge between color face and extrusion wall. 'GRID' centered, filling 72% of frame width. Background: minimalist design workspace — flat dark desk surface, far background shows a large geometric poster pinned to a concrete wall, its primary-color rectangular blocks slightly out of focus. A precision metal ruler edge barely visible at the lower frame. Head-on camera, slight elevation angle. 16:9 format.
