The IBM 80-column punchcard was the universal data-entry medium of mid-20th-century computing — manila card-stock printed with precise grid lines, column numbers, and the IBM logo. This system distills that industrial-information artifact into a design language of warm cream paperboard, hairline black grids, and IBM industrial blue accents, where every column is a character and the constraint is the brand.
IBM 80列穿孔卡是二十世纪中叶美国商业、政府与学术计算的通用数据载体——米黄色卡纸上印着精密网格线与列号。本设计系统将这一工业信息时代的标志性物件提炼为视觉语言：温暖的卡纸底色、发丝般的黑色网格、IBM工业蓝点缀，每一列即一个字符，格式即约束，约束即品牌。
