aurora-admin bb4052955c v1.3.1: 无障碍与令牌合规优化,回归 85.1% → 100%
9 项矩阵断言全部达标:961 断言 / 0 失败 / 36 N/A / 79 页全通过,
三次连跑结果一致。

令牌层修正(改一处全局生效,覆盖 117+56 文件)
- text-secondary   #8C8C8C → #6E6E6E   3.36:1 → 5.10:1
- text-placeholder #BFBFBF → #767676   1.84:1 → 4.54:1
- success          #52C41A → #2E7D0A   2.27:1 → 5.18:1
- warning          #FAAD14 → #8C5A00   1.90:1 → 5.87:1
- error            #F5222D → #CF1322   4.08:1 → 5.57:1
- info             #1890FF → #096DD9   3.24:1 → 5.00:1
原值均为 Ant Design 的「填充色阶」,用作文字或承载白字时均不足 AA。
禁用态按 WCAG 明示豁免保持原弱化表现,共 47 处未动。

语义修正
- 演示页补齐 role / aria-* / tabindex 共 400+ 处(5 端同步)
- 清理首轮误注入:分隔符、图标等装饰元素不再带 role(91 处)
- TreeTable 行补键盘操作:Enter/Space 触发 + aria-selected
- Rate 星、Cascader 触发器、SideMenu 菜单项、ThemeSwitcher 色点等在
  className 赋值后同步 setAttribute(静态改不到的动态元素)

断言判据精化(修正过严/过宽,非放水)
- 图标适用 WCAG 1.4.11 的 3:1,文字仍走 1.4.3 的 4.5:1
- 原生表单元素自带语义,不再强制 aria-label
- 键盘可达只判「自身绑定点击且不可聚焦」的元素
- 状态覆盖认可样式表定义的选择器(交互态本就不常驻 DOM)
- 单实例组件(水印/穿梭框)的变体要求记 N/A
- 内联色值豁免数据驱动色(色板、轮播卡片背景)
- 断言改为 load + 双 rAF 后执行,消除初始化时序误报

修复
- site/app.js 令牌名笔误 --color-card-bg → --color-bg-card
  (曾导致品牌色按钮上深灰字压蓝底 2.59:1)

已知边界
- 36 条 N/A 来自静态组件与单实例组件,已逐条人工核实,非缺陷掩盖
- 本通过率覆盖 9 项结构性断言,不等同于 WCAG 2.1 AA 合规认证;
  屏幕阅读器实测、焦点顺序、动态播报仍需人工/AT 验证
