 - 优先使用 `canvasThemes`、`useThemeStore` 或 Ant Design `ConfigProvider` token。
 - 不要硬编码黑白、stone、slate 等颜色导致浅色/深色主题不一致。
 - 新增画布按钮、弹窗、浮层时，尽量复用已有工具栏、节点面板、Modal 的视觉风格。
+- 画布顶部工具栏和状态信息优先采用极简扁平风格：无边框、无阴影、无胶囊背景，融入整体背景，弱化按钮感，仅保留轻微 hover 反馈，保持简洁现代、低视觉重量。
 - 图片节点尺寸逻辑要尊重原始比例，除非功能明确要求自由变形。
 - 批量生成、多图展示、助手面板等画布交互要尽量简洁，不要占用过多画布空间。

 # 待测试

- 模型选择器改为共享的 shadcn 风格下拉，按模型名称显示 OpenAI、Claude、Gemini 图标，并把画布节点下方、右侧助手和配置弹窗统一到同一套组件；右侧助手的模型和模式按钮会随工具栏宽度自动在文字态和图标态之间切换，需要确认生图页、画布助手、节点配置和配置弹窗中的选中态和下拉列表显示正常。
- 画布图像设置里的尺寸输入去掉了原生数字步进箭头，需要确认宽高仍可直接输入、禁用态正常、设置值回写正常。
- 后台提示词定时同步默认改为开启且默认每 5 分钟执行一次，需要确认新环境未保存过设置时开关默认打开、Cron 默认值正确，用户手动关闭或修改 Cron 后能保持配置。
- 画布右侧助手和节点下方对话框的生图设置弹层改为紧凑图像设置面板，面板只包含质量、尺寸、宽高比和生成数量选择，模型选择保留在对话框底部工具栏；需要确认助手内设置面板不会被右侧面板裁切，节点内质量可正常选择并参与生成、尺寸可编辑、宽高比预览显示正常且为直角矩形、auto 不重复显示、张数每行 4 个且自定义输入框能显示当前值、实际生图参数正常；节点设置面板打开时会隐藏节点悬浮工具条，避免遮挡质量选择。
- 管理后台 `/admin/prompts` 新增提示词批量删除，需要确认多选、确认弹窗、删除后列表刷新和筛选条件下删除行为。
- 管理后台 `/admin/settings` 的私有配置新增提示词定时同步开关和 Cron 表达式；开启后后端会按配置同步内置 GitHub 远程提示词源，需要确认保存配置和到点同步行为。
- 管理后台 `/admin/settings` 中的渠道模型列表获取和模型测试已改为走后端接口，前端不再直接读取或转发 API Key，需要确认保存后、编辑中和已有渠道三种场景都能正常拉取模型和测试连通性。
- 提示词远程源新增 `davidwuw0811-boop/awesome-gpt-image2-prompts`，同步时会读取仓库 `prompts.json` 的结构化数据，需要确认后台同步后分类、封面图、标签和提示词内容展示正常。
+- 修复生图工作台和画布生图请求中 `quality` 参数可能传入上游不支持值导致 400 的问题；请求前会归一化质量枚举，`auto` 或异常值不再发送给上游。
+- 管理后台新增/编辑渠道时，渠道可用模型支持通过弹窗按“新获取、已有”分组选择，并可在弹窗内手动增加模型或拉取模型列表后再写回表单。
+- 管理后台编辑渠道时，API Key 留空不再触发必填校验，表示沿用已保存的密钥；新增渠道仍要求填写 API Key。
+- 管理后台公开配置里的系统可用模型候选项改为由已启用渠道中选择的模型合并去重生成，最终开放哪些模型仍由公开配置里手动勾选。
+- 视频生成请求参数对齐 `grok-imagine-video` 接口：使用 `resolution_name`、`preset=normal`、`input_reference[]`，支持清晰度、尺寸、秒数快捷选择和手动输入，并支持最多 7 张参考图。
+- 画布视频设置浮层改为挂载到页面根层级，避免被节点悬浮工具栏遮挡。
+- 视频清晰度输入框改为只输入数字，提交请求时再拼接 `p` 单位。

 # TODO

 本文档用来记录当前项目后续比较值得处理的事项。
-
-## P0 近期优先
-
-暂无。
-
-## P1 核心账号和后台
-
- 登录注册和用户模块：新增 `users` 表，用户角色、算力点余额、邀请码、邀请人、邀请人数和第三方平台用户 ID
-  等直接放在用户表字段里；补齐登录、注册、第三方登录、用户信息、管理员用户管理等基础能力。
- 字典管理：新增 `dicts` 表，一个字典一行，具体字典项用 JSON 保存；用于维护分类、标签、业务枚举、模型分类、日志类型等可配置项。
- 日志管理：新增 `credit_logs` 记录用户算力点变更流水，新增 `api_logs` 记录第三方大模型 API 调用情况。
- 对话工具调用：在助手对话中增加类似工具调用的形式，展示模型调用、生成图片、插入画布等步骤。
- 画布助手对话框优化：把当前对话面板调整得更简洁，减少干扰，突出输入、引用和结果。
- 考虑引入视频生成能力
-
-## P1 算力点和商业化
-
- 算力点模块：使用 `users` 表里的算力点余额字段，用于调用后端生图、文本等接口时扣除；扣除记录写入 `credit_logs`。
- 算力点订阅模块：订阅套餐配置先放 `settings.public.value`，用户订阅记录新增 `subscriptions`
-  表；用户购买订阅后，模型调用优先从可用订阅额度扣除，不足时再扣用户余额。
- 支付模块：新增 `orders` 表，统一记录充值、订阅购买等订单，预留 Linux LDC 支付和第三方聚合支付；该模块优先级较低，先只设计结构，暂不重点实现。
- 邀请奖励模块：邀请码、邀请人和邀请人数放 `users`，注册奖励、充值奖励配置放 `settings.private.value`，奖励发放记录写入
-  `credit_logs`。
-
-## P1 内容、素材和画布
-
- 文件存储管理：新增 `files` 表和存储接口，文件表只记录最终可访问 URL 等基础信息；后续再考虑图片缩略图、文件清理等能力，后台可查询所有图片和文件。
- 提示词管理：新增 `prompts` 表，公开提示词、内置 GitHub 系统提示词、分类和扩展信息等尽量放字段或 JSON，支持后台维护和随时爬取更新。
- 提示词分类：已移除 `prompt_groups` 表；分类数据很少，并且必须和抓取代码一一对应，直接在代码内存里写死维护。
- 画布管理：新增 `canvases` 表，后台管理员可以查看每个人的画布数据，普通用户可以查看自己的画布列表。
- 公开画布：在 `canvases` 表增加公开状态、审核状态、公开信息等字段；管理员可将自己的画布设为公开，用户也可以申请公开并由管理员审核。
- 画布分享与模板：在云端画布基础上支持只读分享、复制为模板、团队内共享，分享配置和模板标记优先放在 `canvases` 字段或 JSON 中。
- 项目库：基于公开画布增加系统公开项目库，用于筛选、打开、复制公开画布项目。
- 画布协作能力：后续如果支持多人协作，协作成员、节点操作事件、锁定/光标、冲突处理和增量同步优先放在 `canvases` 的协作 JSON
-  中，确实不够用时再拆表。
- 素材管理和我的素材：新增 `assets` 表，用 `user_id`、`visibility`、`type` 区分系统公开素材和用户私有素材；管理员可管理公开素材，也可以查看每个用户自己的素材。
- 素材互动：公开素材增加点赞量、收藏量、查看量等统计字段；用户侧我的收藏、我的点赞先放在 `assets` 或用户偏好 JSON
-  中，后续数据量大了再拆互动表。
-
-## P2 体验和工程
-
- 接口调用队列：图片/文本生成接口增加队列、并发限制、后台状态和基础失败处理，避免大量请求直接打到模型渠道。
