+## 新增 /en/ 登录注册页（20:02）
+- 用户要求：把 /en/ 下的 login 和 register 做出来，符合当前网站设计。
+- 背景：Astro i18n `prefixDefaultLocale: true`，导航 Login/Signup 链接解析为 `/en/login`、`/en/register`，但这两个文件之前不存在（只有根 `src/pages/login.astro` 等 ComingSoon 占位），点开 404。
+- 改动（加法式，不动根 ComingSoon 页、不动原 Login.astro/Register.astro 组件）：
+  1. `src/lib/api.ts`：新增 `saveSession(token, user)`，写入 `fa_token`/`fa_user`（与 `getUser`/`fetchMe` 共用 key），供登录/注册后落地本地会话。
+  2. 新建 `src/components/pages/AuthForm.astro`：登录/注册通用编辑风表单（props `mode: 'login'|'register'`）。
+     - 设计：沿用全站黑白极简编辑风——monospace 顶边 kicker（Account / Sign In|Create Account）、`font-serif font-black` 大标题、monospace 副标题、黑底描边 input（`auth-input`）、黑底白字描边按钮（hover 反白，沿用 `cs-btn` 调性）、底部 footer 链接（注册↔登录互链）。容器用 `w-full max-w-[460px] mx-auto`（避免 m-auto shrink-to-fit，见 MEMORY Layout 陷阱）。
+     - 客户端 `<script>`（module，可 import）：读 `form.dataset.mode/redirect`；提交 POST `/api/auth/login` 或 `/api/auth/register`（body JSON），成功 `saveSession` 后 `location.href = redirect`（优先 `?redirect=`，否则 `/en/`）；失败/网络错在 `auth-error` 内联显示；注册时校验两次密码一致。后端不可用时优雅报错，不破坏设计。
+  3. 新建 `src/pages/en/login.astro`、`src/pages/en/register.astro`：套 `<Layout>` + `<AuthForm>`。
+  4. `src/layouts/Layout.astro`：原来 `<title>{`111`}</title>` 硬编码 bug，改为支持 `title` prop（`${title} — Portfolio Studio`）。属于让新页面标题正确的必要小修；导航(header)未动。
+- 验证：`npm run build` BUILD_EXIT=0；AuthForm/两个 page/Layout `read_lints` 全 0；`dist/client/en/login/index.html`、`en/register/index.html` 均含 `auth-form`/`auth-input`/对应标题；`python -m http.server 8088` 托管 dist/client，`/en/login/`、`/en/register/` 均 200。
+- ⚠️ 范围说明：仅做了 /en/ 版。根 `/login`、`/cn/login`（及 register 对应）仍是 ComingSoon 占位，未动。若要补齐 /cn/ 与根版，需再建 `src/pages/cn/login.astro` 等（可复用 AuthForm）。后端 `/api/auth/login|register` 是否就绪未知，未接时提交会显示内联错误。

 - **所有走秀页 `/shows`**（新建 2026-08-08）：全局走秀档案（区别于 `/articles` 的品牌档案视图 ?brand_id）。基于 articles.astro，标题「All Runway」，保留系列/季节/品牌筛选 + 三视图(Grid/Magazine/Timeline)，新增分页 Load More（page/total/busy，append 模式，后端 `?page=&size=30&with_images=5`）。首页 sec-more「全部走秀 →」指向 /shows。
 - 其余模块(Portfolio / Latest Projects / About / Contact / 登录注册)为「暂未上线」占位页：直接访问旧 URL 或点击导航旧链接均渲染 ComingSoon 占位；**导航(header)保持原样未改动**（用户 2026-08-07 明确「header 别动」），门禁完全靠占位页实现。
 - **首页 tabbar**（index.astro, id="tabbar"）：仅「发布会(backstage)」上线（默认激活 + Live 徽标，承载 getShows(8) SSR 真实卡片）；「灵感(shows)/社媒(events)/街拍(street)」标 `data-soon="true"` + Soon 灰徽标，点击仅显示 ComingSoon 占位、不再请求后端；「品牌」tab 仍为指向 /brands 的有效链接（属已上线模块，未屏蔽）。
-- 占位实现：src/components/ComingSoon.astro（编辑风，props: module / moduleZh / note；两个按钮「浏览走秀档案 →」「返回首页」）。6 个页面(portfolio / latest-projects / about / contact / login / register)改为 `<Layout><ComingSoon/></Layout>`。
-- login/register 原 standalone 页（未 import global.css、字体变量未定义），已改为套 Layout + ComingSoon 占位页，顺带修复字体一致性；导航中 Login/Signup 链接保留，点击即见占位。
+- 占位实现：src/components/ComingSoon.astro（编辑风，props: module / moduleZh / note；两个按钮「浏览走秀档案 →」「返回首页」）。portfolio / latest-projects / about / contact 仍为 ComingSoon 占位页。
+- **登录/注册（2026-08-25 更新）**：`/en/login`、`/en/register` 已做成真实编辑风页面（套 Layout + 新建 `src/components/pages/AuthForm.astro` 通用表单组件，`mode:'login'|'register'`，客户端 POST `/api/auth/login|register`，用 `saveSession` 写 `fa_token`/`fa_user`）。根 `/login`(src/pages/login.astro) 与 `/cn/login` 等**仍是 ComingSoon 占位**（未动，属当时范围外）；导航 Login/Signup 在 en 语境下现指向真实的 /en/login、/en/register。
