“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. Square 1:1. SIGNAL as precision fractured glass letterforms perfectly centered at 78% frame width. Each letter shows clean geometric fracture patterns following mathematical stress lines — Voronoi tessellation-like crack networks dividing letter surfaces into precise angular panels, each panel a flat glass face with distinct reflective properties. Deep charcoal-to-navy background with faint technical grid texture. Hard overhead spotlight: front panels catch brilliant white specular highlights; adjacent panels at precise angles reveal cool blue-grey glass depth at panel edges. Crack lines are razor-thin concentrated white light seams. The letters retain complete readability — fractured, not shattered. Each letter reads as a precision-engineered glass object with controlled fracture maps, like structural glass under calculated stress. Cold technical precision — the language of engineering failure analysis made typographic.
