"Bassline Kai — Next Set in 5" 是一张 DJ 直播的中场画面，采用霓虹舞台风格。艺名和倒计时那行用发光紫字放在中央，下面是一道翻滚的紫色声波，聚光灯照在反光的舞台地面上。可以换成你自己的名字和中场语。

Create a finished 16:9 full-screen intermission overlay for a DJ stream, 1824 × 1024 px. Render exactly these two text strings, with exact spelling and casing: “Bassline Kai” and “Next set in 5”. No other words, numbers, logos, interface elements, fake chat, or viewer counts. Make “Bassline Kai” the dominant channel-name wordmark, bold and instantly recognizable at phone-thumbnail size; set “Next set in 5” beneath it as a large, clearly readable status line. Use custom ultra-heavy geometric sans lettering with wide proportions, thick even strokes, squared construction, generous counters, and clean spacing. Form luminous neon-purple letter faces with a bright violet core, restrained lavender edge bloom, and crisp contours; prioritize legibility over glow. Place both text lines centrally within generous safe margins. Behind and around the lettering, build broad, flowing purple sound-wave ribbons and an audio waveform from fine luminous strokes, concentrated toward the lower third and outer sides so the central type remains unobstructed. Depict a dark, empty performance stage with a near-black backdrop, subtle stage haze, faint violet floor reflections, and a few restrained purple light beams; no people or equipment. High-contrast neon lighting, clean graphic composition, polished digital render, restrained atmosphere, crisp edges. Keep the background dark and uncluttered, with no small edge text.
