Office Document (Calibri 2007)

Office Document is the look of a Word file being written: a crisp white page sheet floating on a soft light-gray workspace, set in Calibri — the rounded humanist sans that Microsoft made the world's default in 2007. Office-blue and dark-blue headings, hairline-ruled tables, and standard page margins give it the neutral, legible authority of memos, reports, and proposals.

This system distills that ubiquitous business-document grammar into a design language: restrained, grid-disciplined, and quietly professional, where clarity outranks ornament.

Office Document 还原的是"一份正在撰写的 Word 文档"：一张洁白的页面浮在柔和的浅灰工作区之上，正文用的是 Calibri——微软在 2007 年定为默认字体的那款圆润人文无衬线体。Office 蓝与深蓝标题、细线表格、标准页边距，赋予它备忘录、报告与提案那种中性、易读、不张扬的专业气质。

本设计系统将这种无处不在的商务文档语法提炼为一套设计语言：克制、网格分明、安静而专业，让清晰始终压过装饰。
