 证据：
 
 - `app/login/page.tsx:11`：默认登录 Logo 不再指向不存在的 `/logo/logo2.png`，没有配置时直接走文字占位。
+- `app/api/system-settings/route.ts`、`app/login/page.tsx`：公共系统设置现在返回注册开关；登录页不再固定展示“立即注册”，注册开启时改为“申请加入”，关闭时提示联系管理员开通。
 - `app/login/page.tsx:295`：登录页已改为浅灰背景和中性表单，不再使用浅蓝渐变背景。
 - `app/register/page.tsx:21`：注册页已改为和登录页一致的浅灰背景。
 - `app/register/page.tsx:88`：注册页已增加默认 Logo 兜底，没有配置图片时显示文字占位，不再显示破图。
 - `app/complete-profile/page.tsx:25`：完善资料页已改为和登录页一致的浅灰背景。
 - `app/complete-profile/page.tsx:205`：完善资料页已增加默认 Logo 兜底。
-- `app/activate/page.tsx`：激活页已完成第一轮收口，激活表单、激活成功页和免费试用弹窗统一为浅灰背景、普通边框、`rounded-lg` 和轻阴影；许可证输入去掉大字距和偏展示页的大号字体，蓝色主按钮改为中性深色按钮。
+- `app/activate/page.tsx`：激活页已完成第二轮收口，默认只展示许可证密钥激活；“免费试用/购买许可证”入口已改为显式环境开关下的“自助试用”，客户默认安装现场不再露出公网获客口径。
 - `app/dingtalk-callback/page.tsx`：钉钉回调页已完成第一轮收口，蓝色渐变整屏背景改为浅灰背景，`rounded-2xl shadow-xl` 大卡片改为 `rounded-lg border shadow-sm` 普通状态卡片，加载/成功/失败状态复用同一个中性外壳。
 - 代码复扫：`app/dingtalk-callback/page.tsx` 已无 `bg-gradient`、`rounded-2xl`、`shadow-xl`、大尺寸状态图标等命中。
 - 验证限制：本轮尝试用 Codex 内置浏览器打开钉钉回调页时返回“没有可用活动面板”，因此该页暂未补截图；已完成 `npm run type-check` 和 `npm run lint` 验证。
 
 建议动作：
 
-- 登录、激活、回调、完善资料页统一成同一套私有化安装/访问风格；钉钉回调页和激活页已完成第一轮视觉收口。
+- 登录、激活、回调、完善资料页统一成同一套私有化安装/访问风格；钉钉回调页和激活页已完成第一轮视觉收口，激活页公网试用/购买口径已进一步隐藏。
 - 背景用纯色或轻灰，不用大面积渐变。
 - 登录页可以保留品牌感，但减少泛 SaaS 视觉：小 Logo、清晰表单、明确客户系统名称即可。
