rendered as a three-dimensional holographic projection — letterforms constructed from luminous Delaunay triangulation mesh with razor-thin electric blue wireframe edges (RGB 0,160,255) forming the skeletal structure of each letter. Letter volumes are semi-transparent with inner glow: cold white core fading to electric blue at the edges. A horizontal scan beam of pure white-blue light sweeps across the letter surfaces. Letter surfaces have a glass-thin depth — exactly 15-20% letter-width thickness with beveled top face. Sharp neon blue outer glow halo radiates 4-6px around each letter edge. The material reads as: light-projected holographic data rendered by a near-future AI interface. Wide 16:9 carrier. A dark phone screen mockup held in hand — displaying a YouTube video thumbnail with SIGNAL as glowing holographic wireframe text title. The thumbnail has a sci-fi aesthetic. The phone carrier communicates: the futuristic text generator output used in a real YouTube thumbnail seen on mobile.
