"Merch" 是一个街头涂鸦风格的 Twitch 面板标题。带喷漆飞溅的橙色和青绿色厚实涂鸦字铺满一块深色金属框的粗糙水泥牌子。保持这个样式只换标签，就能做出整套。

Create a finished Twitch info-panel header, 21:9 wide and short. Fill the entire frame edge to edge with a concrete-gray surface; no empty bands above or below. Center one broad, shallow concrete plate with chipped corners, fine aggregate texture, shallow bevel, and a narrow dark steel rim. On the plate, render exactly one word, “MERCH”, centered and dominant; do not add any other text, symbols, logos, buttons, or interface elements. Build the letters as custom graffiti lettering with thick, hand-drawn strokes, slightly irregular angular contours, tight spacing, and open counters. Use vivid safety orange and saturated teal in alternating letter faces, with a thin dark charcoal keyline and short extruded charcoal shadow to separate the forms from the plate. Keep the word exceptionally large, occupying roughly 68% of the canvas width and 54% of its height, with clear letter shapes that remain readable when scaled to 320 pixels wide. Graffiti paint is opaque and clean-edged, with restrained overspray and a few small paint flecks close to the letters only; do not obscure the word. Broad frontal light, subtle top-left highlights on the plate bevel, soft contact shadow beneath the plate, crisp high contrast, detailed surface rendering. Keep all important content inside a generous safe margin. No people, props, fine print, or busy background.
