 # OJ2 设计文档：题目详情页重设计
 
 日期：2026-09-28
-状态：**设计已定，第 14 节的 1–4 步和第 7 节已实施**（还没做：5.5 的「我的提交」行内展开与「放回编辑器」、5.2 的例子表格）。效果图在 claude.ai 的私有画布「题目详情页重设计」里（「机房（方案 B）」
+状态：**设计已定，第 14 节的 1–4 步和第 7 节已实施**。效果图在 claude.ai 的私有画布「题目详情页重设计」里（「机房（方案 B）」
 那一页是定稿，「初稿 1280×800」那一页已作废，只留着对照）。效果图表达不了的规则都写在这里，
 **实施时以本文为准**。
