- Login form: `POST /login`.
- Request fields: `username`, `password`, and optional `redirect`.
- Request fields consumed by `LoginServlet`: `username`, `password`, and
optional `redirect`.
- Presentation-only login controls may submit auxiliary fields such as
`loginRole` and `rememberUsername`; these must not participate in
authentication or authorization unless the Servlet/service contract is
deliberately changed.
- Login JSP request attributes: `errorMessage`, `username`, and `redirect`.

- `redirect` must be a same-application path beginning with one `/`; invalid
values are ignored.
- `loginRole` is only a login-intent hint in the JSP. The authenticated role is
determined by the `users.role_code` row returned through `AuthService`, not by
a client-side radio selection.
- Remember-me behavior may persist only the username in browser storage. It must
never persist passwords, password hashes, redirects, permission state, or
extend the server session.
- JSPs render data with JSP EL/JSTL, not scriptlet Java.
- JSPs may read safe session snapshots, but they must not call DAOs or inspect
password hashes.

- Good: failed login keeps the escaped username and never redisplays the
password.
- Good: selecting a role radio option or checking remember-me does not change
the server-side authentication decision.
- Base: dashboard reads `sessionScope.authenticatedUser.displayName` and
`sessionScope.userRole` only for display/navigation.
- Bad: JSP uses scriptlets, JDBC, or raw request parameters to decide
authentication.
- Bad: JSP, JavaScript, or Servlet code trusts `loginRole` to grant a role or

## Goal
精简已登录页面中与侧边栏重复的右侧跨模块跳转按钮，并补充更贴近中文图书馆场景的演示图书与读者数据。

* “新增图书”“新增分类”“新增读者档案”“新增账户”等当前页面内的主要操作仍应保留。
* 演示数据位于 `src/main/resources/db/schema.sql`，当前包含英文读者名、英文分类和英文图书。
* 项目是 JSP + Servlet + MySQL 架构，前端页面在 `src/main/webapp/WEB-INF/jsp/`，数据库初始化脚本使用 `utf8mb4`。
* 用户补充要求：仿照参考截图重构登录界面，必须是真实可用的登录表单，而不是静态展示页。
* 参考截图特征：浅色模糊图书馆背景、居中的白色登录卡片、蓝色书本图标与“图书管理系统”标题、用户名/密码输入框图标、密码显隐按钮、身份单选项、记住我和忘记密码入口、蓝色主登录按钮。
## Assumptions

* 用户账户与角色页面不再显示跳转到读者档案的右侧按钮；保留新增账户入口。
* 数据库初始化脚本加入中文图书分类、中文书名、中文作者和中文读者姓名。
* 本地演示账号仍能用于登录验证。
* 登录页按参考截图重构视觉，但保留现有 `POST /login`、`username`、`password`、`redirect`、错误提示和回填用户名等真实登录能力。
* 登录页新增或保留真实可交互控件：密码显隐切换、登录身份单选项、记住我选项和忘记密码入口。
* 登录身份选择不应破坏现有服务端认证；当前后端仍以账号密码和账号角色为准，前端角色选项仅作为登录意图提示或表单辅助字段。
* 登录页需要在桌面和移动端保持可用，输入框、按钮和错误提示不能溢出或遮挡。

* [x] 密码显隐、记住我、身份单选项在浏览器中可交互且不破坏登录流程。

## Technical Notes
* Likely JSP files: `src/main/webapp/WEB-INF/jsp/reports/dashboard.jsp`, `src/main/webapp/WEB-INF/jsp/books/catalog.jsp`, `src/main/webapp/WEB-INF/jsp/books/manage.jsp`, `src/main/webapp/WEB-INF/jsp/books/categories.jsp`, `src/main/webapp/WEB-INF/jsp/readers/manage.jsp`, `src/main/webapp/WEB-INF/jsp/admin/users/manage.jsp`.
* Login files: `src/main/webapp/WEB-INF/jsp/auth/login.jsp`, `src/main/webapp/static/css/app.css`, and possibly small inline or static JavaScript for password visibility/remember-me interactions.
* Data file: `src/main/resources/db/schema.sql`.
* Relevant specs: frontend JSP/component/state/quality guidelines and backend database/quality guidelines.
* Final verification: `git diff --check`, JSP scriptlet/SQL/JDBC scan, removed-link scan, and `/home/sjy/.sdkman/candidates/maven/current/bin/mvn clean package` passed.
* Spec update decision: no `.trellis/spec/` update needed because this task did not introduce new routes, APIs, tables, cross-layer contracts, or reusable implementation conventions.
* Final verification: `git diff --check`, `node --check src/main/webapp/static/js/login.js`, JSP scriptlet/SQL/JDBC scans, removed-link scan, password persistence scan, and `/home/sjy/.sdkman/candidates/maven/current/bin/mvn clean package` passed.
* Spec update decision: `.trellis/spec/frontend/type-safety.md` documents the new presentation-only login controls (`loginRole`, `rememberUsername`) and the username-only remember-me constraint.
