+# Frontend UI Standards Rules
+
+## Principle
+Use Ant Design as primary UI library with minimal Tailwind CSS. Prioritize mature Ant Design solutions for responsive layouts. Avoid secondary encapsulation unless necessary.
+
+## Technology Usage Guidelines
+- **Ant Design**: Forms, data display, complex interactions (`<Button>`, `<Modal>`, `<Form>`)
+- **Tailwind CSS**: Spacing, layout, simple styling (`className="flex items-center gap-2 text-sm"`)
+- **Inline Styles**: Special cases (`style={{ fontSize: "48px" }}`)
+- **Override AntD**: Use `<style jsx global>` when necessary
+
+## Layout Standards
+
+### Global Layout
+Use Header, Sider, Footer, Content structure. Reference: https://ant.design/components/layout-cn
+
+```tsx
+const { Header, Footer, Sider, Content } = Layout;
+
+<Layout>
+  <Header>Header</Header>
+  <Layout>
+    <Sider width="25%">Sider</Sider>
+    <Content>Content</Content>
+  </Layout>
+  <Footer>Footer</Footer>
+</Layout>
+```
+
+### Responsive Grid
+Use AntD Grid for responsive layouts. Reference: https://ant.design/components/grid-cn
+
+```tsx
+<Row gutter={{ xs: 8, sm: 16, md: 24, lg: 32 }}>
+  <Col span={6}>col-6</Col>
+  <Col span={6}>col-6</Col>
+  <Col span={6}>col-6</Col>
+  <Col span={6}>col-6</Col>
+</Row>
+```
+
+### Flex Layout
+Use AntD Flex for component alignment. Reference: https://ant.design/components/flex-cn
+
+```tsx
+<Flex vertical className="h-full overflow-hidden">
+  <Row><Col>Content 1</Col></Row>
+  <Row><Col>Content 2</Col></Row>
+  <Row className="flex:1 min-h-0">
+    <Col><Flex className="h-full overflow-hidden">...</Flex></Col>
+  </Row>
+</Flex>
+```
+
+## Component Standards
+
+### Modals
+1. **Complex Modal**: For reusable modals with custom content
+2. **Simple Modal**: Use `useConfirmModal` for one-time confirmations
+
+#### Modal Standards
+- Use `centered` for positioning
+- Confirm buttons: `type="primary" danger={true}`
+- i18n keys: `common.cancel`, `common.confirm`
+- Icon: `<ExclamationCircleFilled />` aligned with title
+
+```tsx
+// Complex modal
+<Modal
+  open={isOpen}
+  centered
+  okButtonProps={{ type: "primary", danger: true }}
+  okText={t("common.confirm")}
+>
+  <div className="flex items-start gap-4">
+    <ExclamationCircleFilled style={{ color: token.colorWarning, fontSize: '22px' }} />
+    <div>
+      <div className="font-medium">{t("title")}</div>
+      <div className="text-sm">{t("content")}</div>
+    </div>
+  </div>
+</Modal>
+
+// Simple modal
+const { confirm } = useConfirmModal();
+confirm({
+  title: t("delete.confirmTitle"),
+  content: t("delete.confirmContent"),
+  onOk: () => { /* ... */ }
+});
+```
+
+### Icon Library
+- **Primary**: `lucide-react` for consistency
+- **Fallback**: `@ant-design/icons` when lucide-react lacks icons
+
+```tsx
+import { ExternalLink } from "lucide-react";
+import { PlusOutlined } from '@ant-design/icons';
+
+<ExternalLink />
+<PlusOutlined />
+```
+
+## i18n Usage
+
+```tsx
+import { useTranslation, Trans } from "react-i18next";
+
+// Simple text
+t("common.confirm")
+
+// HTML content
+<Trans
+  i18nKey="modal.description"
+  values={{ title }}
+  components={{ strong: <strong /> }}
+/>
+```
