怎么填变量：第一行把品牌名、行业、主色、辅色、起源地全部换成你自己的；[麻薯、茶筅] 换成能代表你业务的 1–2 个小物件（咖啡店写"咖啡豆、拉花杯"）。品牌名建议 4–10 个字母的英文或拼音，中文品牌名可以写拼音并在 (5) 里改成"中文品牌名作为次要文字"。

常见问题：

• 出现了真实大牌的 Logo：原帖是拿知名品牌做的二创，商用有侵权风险。本站版本只用于自己的品牌，不要填别人的商标。
• 颜色太多、不像贴纸：重复"最多 4 种颜色、零渐变"。
• 片假名写错：不需要日文就删掉第 (5) 项和对应的"片假名"要求。

迭代：定稿后追问"同一徽章做成圆形版本"，一套贴纸周边就有了两个形状。

[BRAND NAME]

You are a senior vector designer specializing in Y2K Harajuku badge art. Your world: Tokyo bootleg culture, early 2000s Japanese brand remixes, retro-futuristic sticker aesthetics. Every output should look like a clean Illustrator vector file, flat and sticker-ready. The badge structure must be invented fresh for each brand, not templated.

BRAND ANALYSIS

Before designing, resolve all of the following: (1) PRIMARY COLOR — brand's main color softened into a pastel Y2K version, still recognizable but lighter and more kawaii; (2) ACCENT COLOR — brand's secondary color pushed to warm saturation for energetic pop; (3) DARK COLOR — deep brand palette (navy, dark brown, near-black) used for outlines and extrusions; (4) LETTER CONTENT — brand name in bold lowercase or most iconic abbreviation; (5) KATAKANA — correct Japanese transliteration as a secondary text element; (6) ORIGIN FLAG — brand's country of origin flag as a small flat element; (7) SHAPE LANGUAGE — iconic geometric forms from the brand's visual identity used as orbital and background elements, never generic ovals; (8) CULTURAL SYMBOLS — 1-2 small iconic objects from the brand's universe rendered as tiny flat illustrations; (9) COMPOSITION LOGIC — design the badge layout using everything above so it feels invented specifically for this brand.

CANVAS

1:1 square. Flat off-white or warm light grey background. Completely empty, no texture, no gradient.

BADGE STRUCTURE

Using the resolved shape language and composition logic, build the full badge. Fixed rules: central lettering element, surrounding brand-specific shapes with z-layer stacking, at least one element passing both behind and in front of the letters for depth, and a unified badge or patch silhouette. The shapes must feel inevitable, as if they could only belong to this brand. Everything else is determined by the brand's own visual DNA.

LETTERING

Brand name in large bold lowercase with a wide rounded display typeface. Flat PRIMARY COLOR fill. Thick DARK COLOR extrusion offset down-right at 8-12% of letter height. Bold DARK COLOR outline. No gradients, no rendering.

Y2K SIGNATURE ELEMENTS

Every badge must include: SPEED LINES or motion texture in ACCENT COLOR inside background shapes. SHARP 4-POINT STAR as a decorative accent near the lettering in DARK COLOR. KATAKANA transliteration tucked naturally into the composition. ORIGIN FLAG as a small accurate flat element. BRAND CULTURAL SYMBOL rendered as a tiny flat illustration integrated into the badge.

TECH SPECS

Flat vector only. Zero gradients, effects, blur, or rendering. Clean crisp edges throughout. Maximum 4 colors: PRIMARY pastel, ACCENT warm saturated, DARK outline, off-white. Must feel like a collectible sticker or embroidered patch. Every brand produces a structurally different badge because every brand has different shape language. The Y2K Japanese aesthetic is the constant, the structure is the variable.
