New market_regime_service computes a benchmark (SPY) trend from its 50/200-day SMAs, cached in a SystemSetting and refreshed by a nightly job; GET /market/regime exposes it. Dashboard shows a regime banner; setup cards flag a counter-trend caution when a setup fights the regime (LONG in a bearish market / SHORT in a bullish one). Informational only — nothing is suppressed. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
