maogeigei 5f5b4f1cb7 feat(MCN工作台): 数据功能页+图标扁平化+多项UI优化

- 工作台大版本升级：hash 路由 + 6 数据功能页（周榜/热门账号/账号详情/视频详情/AI写脚本/AI写作复盘），只读复用 dsh 库副本 + 抖音榜单 JSON
- 数据库隔离：复制 dsh 库到 mcn-work-shop/，与 dsh 原库各访问各的（已 gitignore）
- 图标全面扁平化：Lucide 线性 SVG，功能图标亮色区分，文字标题去图标
- 首页重构：功能入口卡 + AI写剧本快捷卡片(2列/8个/5行预览) + 独立帮助页 + header 精简
- 新增设计技能 impeccable + taste-skill（生成网页时参考）
- 修复：fmtTime 跨 script 全局冲突(P0)、弹窗关闭、外链新标签打开等

Extract Flow

Identify reusable patterns, components, and design tokens, then extract and consolidate them into the design system for systematic reuse.

Step 1: Discover the Design System

Find the design system, component library, or shared UI directory. Understand its structure: component organization, naming conventions, design token structure, import/export conventions.

CRITICAL: If no design system exists, {{ask_instruction}} before creating one. Understand the preferred location and structure first.

Step 2: Identify Patterns

Look for extraction opportunities in the target area:

Repeated components: Similar UI patterns used 3+ times (buttons, cards, inputs)
Hard-coded values: Colors, spacing, typography, shadows that should be tokens
Inconsistent variations: Multiple implementations of the same concept
Composition patterns: Layout or interaction patterns that repeat (form rows, toolbar groups, empty states)
Type styles: Repeated font-size + weight + line-height combinations
Animation patterns: Repeated easing, duration, or keyframe combinations

Assess value: only extract things used 3+ times with the same intent. Premature abstraction is worse than duplication.

Step 3: Plan Extraction

Create a systematic plan:

Components to extract: Which UI elements become reusable components?
Tokens to create: Which hard-coded values become design tokens?
Variants to support: What variations does each component need?
Naming conventions: Component names, token names, prop names that match existing patterns
Migration path: How to refactor existing uses to consume the new shared versions

IMPORTANT: Design systems grow incrementally. Extract what is clearly reusable now, not everything that might someday be reusable.

Step 4: Extract & Enrich

Build improved, reusable versions:

Components: Clear props API with sensible defaults, proper variants for different use cases, accessibility built in (ARIA, keyboard navigation, focus management), documentation and usage examples
Design tokens: Clear naming (primitive vs semantic), proper hierarchy and organization, documentation of when to use each token
Patterns: When to use this pattern, code examples, variations and combinations

Step 5: Migrate

Replace existing uses with the new shared versions:

Find all instances: Search for the patterns you extracted
Replace systematically: Update each use to consume the shared version
Test thoroughly: Ensure visual and functional parity
Delete dead code: Remove the old implementations

Step 6: Document

Update design system documentation:

Add new components to the component library
Document token usage and values
Add examples and guidelines
Update any Storybook or component catalog

NEVER:

Extract one-off, context-specific implementations without generalization
Create components so generic they are useless
Extract without considering existing design system conventions
Skip proper TypeScript types or prop documentation
Create tokens for every single value (tokens should have semantic meaning)
Extract things that differ in intent (two buttons that look similar but serve different purposes should stay separate)
