N 添加对角线笔画（█▄ █），G 添加内横杠（█ ▀█），
避免与 O 字母造型雷同。同步更新 ui.ts 中的硬编码 wordmark。

+
+Use your github-triage tool to triage issues.
+
+This file is the source of truth for ownership/routing rules.
+
+Assign issues by choosing the team with the strongest overlap. The github-triage tool will assign a random member from that team.
+
+Do not add labels to issues. Only assign an owner.
