- TrendCard: price, RSI, ATR, slopes, momentum, 52W range all at selected date
- RegimeCard: 5 signals recomputed at selected date; regime label from server
- Date badge above cards; blue tint when browsing history, grey on last date
- instrument_service.py: end_date in events; price_data built before events block

The docker-compose mounts db_data named volume at /app/data which hid the
instruments.json file baked into the image. Moving to /app/config which is
not volume-overlaid resolves the FileNotFoundError on startup.
