“SIGNAL”是使用 FontVibe AI 创作的碎玻璃文字效果。碎裂成锋利的玻璃碎片向外爆开——刀刃般的碎片从撞击中心呈放射状迸射，伴随锯齿状的裂纹。电影级的高冲击破坏质感。

shattered broken glass letterforms — each letter exploded from a central impact point with radial spiderweb crack networks. Three-tier shard fragmentation: large primary shards near impact core nearly flat; medium secondary shards tilting 15-45° outward; small tertiary splinters detached and floating in mid-air. Every glass shard face shows distinct optical behavior: front-facing shards catch brilliant white specular highlights; tilted shards reveal blue-green glass tint at thick edges; suspended splinters fire needle-sharp white glints from all four edges; crack intersections scatter concentrated white light. Peak visual moment: a constellation of needle-thin edge-glints from every floating shard — glass frozen mid-flight at maximum kinetic energy. Wide 16:9. A YouTube tech channel banner or video title card — deep dark navy background, clean and premium. SIGNAL as precision fractured glass letterforms centered with generous horizontal breathing room, geometric fracture maps reading clearly against the dark background. Hard overhead cold spotlight: brilliant white primary panels, cool blue-grey depth panels, glowing crack seams tracing the mathematical fracture lines. Minimal, controlled, authoritative — no chaos. Fractured glass font used for tech YouTube channel banners, coding tutorial video headers, cybersecurity content channel art, and professional technology content creator branding.
