feat: V5.2 frontend differentiation - strategy tabs, side-by-side scores, visual badges

- Paper page: prominent strategy tabs (全部/V5.1/V5.2) at top
- Paper trades: strategy column with color-coded badges (blue=V5.1, green=V5.2)
- Paper positions: FR/Liq scores displayed prominently for V5.2
- Signals page: side-by-side V5.1 vs V5.2 score comparison cards
- Signals page title updated to 'V5.1 vs V5.2'
- New API endpoint for strategy comparison data
- Layout: local font fallback for build stability

+# V5.2 Frontend Differentiation Task
+
+## Problem
+V5.1 and V5.2 currently share the same pages. Boss wants clear visual separation.
+
+## Requirements
+
+### 1. Signals Page (/signals) - Side-by-side comparison
+Currently shows one set of scores per coin. Change to show BOTH V5.1 and V5.2 scores side by side.
+
+For the "Latest Signal" cards at the top, each coin should show:
+```
+BTC  SHORT  V5.1: 80分 | V5.2: 85分  5m前
+```
+
+The V5.2 score should show FR and Liquidation subscores that V5.1 doesn't have.
+
+To get V5.2 scores, add a new API endpoint `/api/signals/latest-v52` that returns the V5.2 evaluation alongside V5.1. Or modify the existing `/api/signals/latest` to include both strategy scores.
+
+### 2. Paper Trading Page (/paper) - Strategy Tabs at TOP
+Add prominent tabs at the very top of the page:
+
+```
+[全部] [V5.1 模拟盘] [V5.2 模拟盘]
+```
+
+When selecting a strategy tab:
+- Current positions: only show positions for that strategy
+- Trade history: only show trades for that strategy  
+- Stats: only show stats for that strategy
+- Equity curve: only show curve for that strategy
+- The "全部" tab shows everything combined (current behavior)
+
+### 3. Visual Differentiation
+- V5.1 trades/positions: use a subtle blue-gray badge
+- V5.2 trades/positions: use a green badge with ✨ icon
+- V5.2 positions should show extra info: FR score and Liquidation score prominently
+
+### 4. Backend API Changes Needed
+
+#### Modify `/api/signals/latest` endpoint in main.py
+Return both V5.1 and V5.2 evaluations. The signal_engine already evaluates both strategies per cycle and saves the primary one. We need to also save V5.2 evaluations or compute them on-the-fly.
+
+Simplest approach: Add a field to the signal_indicators table or return strategy-specific data.
+
+Actually, the simplest approach for NOW: In the latest signal cards, just show the score that's already there (from primary strategy), and add a note showing which strategy it's from. The real differentiation happens in paper trades where the strategy column exists.
+
+#### `/api/paper/trades` already supports `?strategy=` filter (Codex added this)
+#### `/api/paper/stats-by-strategy` already exists
+
+### 5. Key Files to Modify
+- `frontend/app/paper/page.tsx` - Add strategy tabs at top, filter everything by selected strategy
+- `frontend/app/signals/page.tsx` - Show V5.2 specific info (FR/Liq scores) in latest signal cards
+- Backend: may need minor API tweaks
+
+### 6. Important
+- Don't break existing functionality
+- The strategy tabs should be very prominent (not small buttons buried in a section)
+- Use consistent styling: slate-800 bg for active tab, slate-100 for inactive
+- Test with `npm run build`
+
+When completely finished, run:
+openclaw system event --text "Done: V5.2 frontend differentiation - strategy tabs, visual badges, FR/Liq display" --mode now
