"CRASH TEST CLUB" 是一张特技频道的 YouTube 横幅，采用碎玻璃风格。布满裂纹的玻璃字母在碰撞测试假人和一辆撞毁的汽车上方碎裂，旁边是标语「Built to break.」，右下角有一枚圆形徽章。可以换成你自己的频道名、标语和更新日再做一张。

Create a 16:9 YouTube channel banner for a stunt channel. Render all text exactly as written, with clean, highly legible spelling. Composition: deep charcoal-to-black concrete wall, wide cinematic frame. A battered crash-test dummy in a black-and-yellow hazard-striped racing harness stands slightly right of center, cropped from thighs upward, one shoulder turned toward camera. Behind it: a dented steel crash barrier, a crushed silver car door fragment, and a low cloud of glass dust. Harsh directional spotlight from upper left; extreme chiaroscuro; long hard shadows. Primary masthead, occupying 72% width across the upper-middle: “CRASH TEST” on one line and “CLUB” beneath it, enormous custom broken-glass display lettering. Each letter is transparent-to-translucent safety glass shattered from a distinct central impact point: radial spiderweb cracks, large nearly flat shards at the core, medium shards tilted outward 15–45 degrees, tiny detached splinters suspended around the contours. Thick 10–15 mm blue-green glass edges are visible on tilted pieces. Front shard faces catch near-white specular streaks; crack intersections form bright white nodes; every floating splinter fires needle-thin white edge-glints. The wordmark is a frozen windshield explosion, crisp and physically detailed, never melted or smoky. Small uppercase eyebrow at top-left, compact white condensed sans serif: “STUNT CHANNEL”. Lower-left supporting line in white condensed sans serif: “BUILT TO BREAK.” Bottom-left small detail line: “NEW IMPACTS EVERY FRIDAY”. Add a small circular stamped badge at bottom-right reading “CTC // TESTED”. Keep all supporting typography intact, flat white, and separate from glass fragments. Blue-green glints and glass dust travel diagonally from the title toward the dummy. Photorealistic glass VFX, ray-traced reflections, sharp focus, 8k, no extra words, no logos, no watermark.
