“SIGNAL”是使用 FontVibe AI 创作的故障 Glitch文字效果。白色无衬线大写字母被红青通道错位撕开，横向位移切片和扫描线贯穿，倒映在夜里湿漉漉的霓虹街道上。

Core glitch effect: authentic RGB chromatic aberration — red channel shifted 5–8px to the left, cyan channel shifted 5–8px to the right, creating the classic double-vision color split on every letter edge. CRT scan lines: dense horizontal parallel lines across the entire text surface, spacing 3–4px, semi-transparent, rhythmic — simulating a real CRT phosphor screen. Pixel block artifacts: 3–5 sharp-edged rectangular chunks of letter pixels displaced horizontally by 10–25px at random vertical positions along the text. Edge glow: subtle cyan-white phosphor bloom emanating from letter boundaries. The glitch distortion is controlled and deliberate — text remains clearly readable. No random noise flood. No cartoon effects. Professional digital corruption aesthetic. A smartphone screen showing a TikTok or YouTube Short video paused at the opening title card: 'SIGNAL' in glitch text as the video's title, upper-center of the vertical video frame. The underlying video frame is a dark cyberpunk cityscape — neon lights reflected in wet streets, blurred buildings. Phone held by a hand, partial fingers visible at sides. Dark desk background, blurred. 9:16 vertical mobile content aesthetic.
