A finished motorsport number panel graphic that reads exactly "71n" in three large glyphs: the digits 7 and 1 followed by a lowercase-style letter n built to match the digits (same stroke weight, same square proportion, upright). Wide 16:9 frame. The glyphs stand perfectly upright with no lean, each about as wide as it is tall, thick even strokes, wide open counters, set side by side with tight even spacing and filling about 70% of the frame width, centered. Each glyph is a piece of cut gloss vinyl in championship-gold laid onto a satin racing-red painted panel that fills the central band of the image. A thick band of crisp white vinyl runs round the outside of every glyph at one even width, entirely outside the glyph shape, never inside it. The knife-cut edge of the band is visible all the way round, lifting very slightly at the outer corners. The vinyl is glossier than the red panel beneath, so gold, white band and red panel read as three separate tones. A fine line of light catches the upper side of the cut edge and a hairline shadow falls on the panel below it. The edge is crisp enough to pick with a fingernail. Light: a single hard overhead beam, cold white, with a sharp specular streak across the top plane of the vinyl and a deep carbon-black shadow beneath. The panel has a slight sheen and a few tiny paint-fleck textures. The panel edges fade into a pure black night-circuit background with dark asphalt at the bottom edge and a faint painted white line. Fine horizontal white speed streaks trail from the left and right sides of the panel, sharp at the edge and dissolving into darkness, with faint motion haze in the air and a small distant lens flare at upper right. No other text, no logos.
