+Pre-compute backtest results for all strategies, for multiple capital scenarios.
+
+Each strategy is backtested ONCE per market with that market's live starting
+capital (MONITOR_CAPITAL: US $10k, CN ¥70k); the
+resulting equity series is then replayed with different cash-injection
+schedules so we get multiple scenarios without re-running each strategy.
+
+Usage:
+    uv run python precompute_backtest.py [--output PATH] [--years N]
+
+Output JSON shape:
+    {
+        "computedAt": "...",
+        "scenarios": {
