2x2 grid, 16:9, do this for 4 underrated sports: A₁ MID‑CENTURY FLAT VECTOR STYLE (master) clean, flat vector illustration with bold shapes, high contrast, and minimal to no gradients; reminiscent of 1950s/60s commercial art and pulp sci‑fi covers. ¬A₁ = photoreal / 3D render / heavy gradients / painterly. A₂ RETRO‑FUTURISTIC TECH & WARDROBE the subject's gear and clothing are styled in "Atomic Age" or "Googie" retro‑futurism (bubble helmets, finned rockets, ray guns, sleek metallic suits with geometric color‑blocking, dials, antennas). ¬A₂ = modern tech (smartphones, modern spacesuits) / historical clothing / generic sci‑fi. A₃ ATOMIC / GOOGIE COSMOS the background features stylized, geometric cosmic or abstract elements (4‑pointed sparkle stars, ringed planets, atomic orbital rings, abstract boomerang shapes) rather than photorealistic environments. ¬A₃ = photoreal stars / modern UI / empty background / realistic landscapes. A₄ STRICT RETRO PALETTE a limited, vibrant mid‑century color palette (e.g., teal, coral/orange, mustard yellow, cream, deep navy/black) applied as flat color fills. ¬A₄ = neon cyberpunk / pastel / full RGB spectrum / muddy colors. A₅ STYLIZED PROPORTIONS & POSING slightly exaggerated, elegant, or dynamic proportions typical of mid‑century fashion illustration (long limbs, sleek silhouettes, confident posing, stylized facial features). ¬A₅ = anatomical realism / chibi / awkward posing. η HONEST PULP crisp vector edges, intentional halftone dots (optional), bold graphic impact. FORBIDDEN = photoreal · 3D render · modern tech · heavy gradients · realistic space · neon palette · anatomical realism

2x2 网格，16:9，为 4 个被低估的运动项目执行此操作：A₁ 中世纪纤维（Mid‑Century）平面矢量风格（主样式） 干净的平面矢量插画，造型大胆，对比度高，几乎无渐变；让人联想到 1950/60 年代的商业艺术和低俗（pulp）科幻封面。 ¬A₁ = 照片写实 / 3D 渲染 / 厚重渐变 / 绘画感。A₂ RETRO‑FUTURISTIC TECH & WARDROBE 主题的装备与服装采用"原子时代"或"Googie"复古未来主义风格（气泡头盔、带鳍火箭、射线枪、带几何色块的流线金属套装、刻度盘、天线）。 ¬A₂ = 现代科技（智能手机、现代航天服）/ 历史服饰 / 通用科幻。A₃ ATOMIC / GOOGIE COSMOS 背景采用程式化、抽象的几何宇宙或抽象元素（四芒闪光星、带环行星、原子轨道环、抽象回力标形状），而非照片写实环境。 ¬A₃ = 照片写实星空 / 现代 UI / 空白背景 / 写实风景。A₄ STRICT RETRO PALETTE 使用有限而鲜艳的中世纪调色板（如青色、珊瑚/橙、芥末黄、奶油色、深海军蓝/黑色），以平面填色方式应用。 ¬A₄ = 霓虹赛博朋克 / 粉彩 / 全 RGB 光谱 / 浑浊色彩。A₅ STYLIZED PROPORTIONS & POSING 采用中世纪时尚插画典型的优雅或动感略夸张、姿态自信、面部特征程式化的比例。 ¬A₅ = 解剖写实 / Q版（chibi）/ 姿态笨拙。η HONEST PULP 矢量边缘清晰，可选有意半调网点，图形冲击力强。FORBIDDEN = 照片写实 · 3D 渲染 · 现代科技 · 厚重渐变 · 写实太空 · 霓虹调色板 · 解剖写实
