"Race Week Preview" 是一个赛车频道的 YouTube 缩略图，采用速度感赛车风格。粗重的红色斜体大字带着动感拖影，占满潮湿暗色赛道的左半边，头顶一盏探照灯，上方一行频道小字，下方一行短句。每周一期换日期和标题就行。

Create a 16:9 YouTube channel banner, built as a single high-impact racing broadcast ident. Keep all essential text inside the central 70% safe area. Exact text, rendered perfectly: Small top-left kicker: "GRIDLINE CHANNEL" Main two-line headline, dominant: "RACE WEEK" / "PREVIEW" Small lower-left strap: "THE WEEK AHEAD · ON THE LIMIT" Composition: pure carbon-black night-circuit field. The huge two-line headline occupies the center, nearly full safe-area width; "RACE WEEK" above "PREVIEW", aligned left with compressed line spacing. Custom Eurostile Extended skeleton: extremely wide horizontal proportions, bold uniform strokes, precise 90-degree terminals, engineered superellipse counters, squared geometric apertures, mathematical crossbar placement, close-cropped forms. Every glyph leans aggressively forward. Letterforms are high-gloss racing-red lacquer over dark metallic substrate, with a thin championship-gold bevel on upper forward-facing edges. Single hard white overhead/front pit-lane beam creates a crisp specular stripe along every top plane; dense carbon-black shadow is thrown backward in the motion direction. Fine pure-white speed lines originate from the left-facing and trailing edges of every headline letter, remaining crisp beside the strokes and dissolving into horizontal motion haze across the black field. A low band of wet charcoal circuit asphalt anchors the bottom quarter, barely visible, with one thin broken white grid marking. Put a restrained gold telemetry rule and tiny square HUD ticks beneath the strap. Add a dim out-of-focus floodlight bloom at upper right and sparse airborne particulate scatter. High contrast, clean broadcast-grade hierarchy, ray-traced reflections, no cars, no drivers, no logos, no extra text, no rounded lettering, no cyan.
