+# Infinite canvas plan
+
+Scope: only /studio/infinite_canvas, its CSS module, browser interaction checks. Based on main f490543 in isolated worktree. No homepage, graphic, shared authentication or deployment changes.
+
+## Research before implementation
+- Baseline server screenshot captured 2026-10-29: existing server requires dynamic-code authentication before route access. Do not bypass it.
+- Internet image search: AI infinite canvas ComfyUI RunningHub interface; reviewed workflow canvas and media card arrangements. No unlicensed product screenshots copied into product.
+- https://jimeng.jianying.com — prompt-driven creation, image references, canvas.
+- https://klingai.com — attempted primary source; robots denied access. No unsupported detailed claims.
+- https://hailuoai.video — reference input and media-first exploration.
+- https://www.liblib.art and https://www.liblib.tv — Liblib/LibTV reference targets; client-rendered content limits source inspection.
+- https://docs.comfy.org/interface/overview — explicit node workflow and workspace regions.
+- https://www.runninghub.cn — canvas-oriented creation and reusable workflows.
+- https://github.com/bergside/awesome-design-skills — reference catalogue; apply deliberate typography, spacing, accessible controls and consistent hierarchy, without installing external skills.
+
+## Design and behavior
+Dark graphite creation desk with warm lime accent. Narrow left tool rail, large dotted canvas, editable right inspector and floating zoom controls. Start with a clearly labelled sample storyboard: brief → reference → shot plan. Native drag and zoom, selection, editable text/prompt cards, image upload, visible links, add/delete, undo/redo, fit view. Persist bounded browser-local drafts and export/import portable JSON. Images remain local. No simulated generation; generation cards explicitly say model service is not connected. Account link uses existing /account and GET /api/account/session contract.
+
+## Validation
+Local TypeScript and existing tests; local build explicitly authorized for this task. Browser checks for desktop/mobile, creation, drag, undo, reload, JSON export and disconnected AI notice. Clean owned screenshots, build directories and temporary dependency links before delivery. Push branch and open PR against main; no merge or deployment.
+
+## Results
+TypeScript passed; existing 10 tests passed. Project-local Next CLI webpack build passed. Default Turbopack cannot resolve dependencies outside isolated worktree; webpack standalone tracing warns about the temporary dependency symlinks, so deployment artifact completeness is not claimed. Browser smoke passed on desktop and mobile. No deployment performed.

+# Studio Graphic 实施计划
+
+## 研究与范围
+- 改造前证据：ProjectMedia/studio-editor-workspace-qa.png（2026-10-27）；本次在线截图因内置浏览器超时未成功，不当作最新截图。
+- https://github.com/bergside/awesome-design-skills ：参考 token、组件规范、可访问性与质量检查组织方法；其 Stitch 风格不等同于 Google Stitch 产品界面。
+- https://codelabs.developers.google.com/design-to-code-with-antigravity-stitch ：官方界面图参考。
+- https://moda.app/blog/google-stitch-review ：图片搜索找到的多画板与设计系统截图，仅作视觉参考。
+- Figma 的三栏编辑器布局：图层、画布、属性。采用白色工具栏、冷灰点阵底、蓝紫选中态、集中式底部工具条。
+
+## 五个交付阶段
+1. 阅读现有代码、引用 chat，独立分支，协调 infinite_canvas。
+2. 收集参考与截图、明确设计与复用边界，记录计划。
+3. /studio/graphic 实现可编辑画板、图层、历史、保存、导出与同站邮箱账户。
+4. 本地类型、行为、构建和视觉检查；记录真实结果及限制。
+5. 检查完整差异，提交、推送、创建 PR；清理临时产物，等待人工合并。
+
+## 清理边界
+Studio 首页不再展示旧 27 套项目。保留旧路由与数据库，避免破坏现有链接与用户作品；不删除其他 chat 文件。新工作台默认空白，预设只能由用户显式插入。浏览器草稿明确标识本机保存，邮箱账户使用已有 /api/account/* 服务，避免另建身份系统。未配置模型时不提供虚假 AI 生成。
+
+## 分工
+Infinite Canvas 独立 chat 01a18775-33e3-7770-ba63-64b4a6a00c89，仅负责 /studio/infinite_canvas 与专属文件。两分支完成后再评估集成，不自动合并 main。
+
+## 验证记录
+- 用户已确认只清理入口、保留历史数据。
+- 13 项单元测试和 TypeScript 通过。webpack 生产构建通过；默认 Turbopack 被本地 CSS 工作进程端口权限阻止。
+- 自动浏览器检查通过：新增文字/矩形、文字修改、撤销/重做、刷新恢复、SVG 下载、账户弹窗、390px 无横向溢出。截图布局已检查，交付前清理截图。
+- 账户 session 使用访客 fixture；真实邮件注册登录未在本次验证。独立 Studio 本地进程没有账户后端，部署后复用同域 /api/account 服务。
+- 单画板与本机草稿，无云端设计同步、协作或 AI 生成。完整属性编辑以桌面为主。
+- Infinite Canvas 独立 PR #19 已由外部操作合入 main；本分支交付前同步该主线，检查共存。
+
+- standalone 兼容检查通过：27 套历史页面、保存作品读取、旧重定向与渲染 API；测试脚本支持本地 monorepo standalone 路径。
