- app_theme.dart 重写为语义 token(AppColors/AppRadius),落地 primaryStrong/error 等 AA 对比度色 - 五个页面与公共组件的旧靛蓝硬编码色值全部替换为 token,仅换色不动布局 - 新增 BrandMark/AppTextField/PrimaryButton/InlineErrorBanner/AuthScaffold 及 6 个 widget 测试 - 门禁:dart format(0 changed)/ flutter analyze(0 issues)/ flutter test(7 passed) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
