Backend (routers/simulator.py):
- GET /api/simulator/baseline aggregates current market values:
1. macro_gauge_snapshots → VIX, Brent oil
2. FRED economic_events → FEDFUNDS, ECBDFR, DFII10 (real yield)
3. yfinance live → EURUSD=X, ^IRX+^FVX interpolated US 2Y,
DE2YT=RR EU 2Y (or ECB rate +15bps fallback),
^VIX, BZ=F
- Returns sources dict so frontend can show data provenance
Frontend (EuroSimulator.tsx):
- Fetch /api/simulator/baseline on mount; use as base anchors
- compute(p, base) now takes dynamic base instead of hardcoded constants
- Reset button returns to today's live baseline, not hardcoded fallback
- Live/Fallback status badge with fetch date
- Sources panel showing data origin per field
- Chart reference line updates to show live base values

At baseline (deviation=0) the colored bar had width=0 and disappeared.
Added a 2px vertical tick mark at the current slider position so the
handle location is always visible even when there's no deviation.

Slider was computing mid = (0 - 10) / (60 - 10) * 100 = -20% for VIX
(0 outside the 10-60 range), causing the colored track to start at a negative
left position and overflow the container.
Fix: add overflow-hidden on the track div; add center prop (defaults 0)
that the caller sets to the actual baseline value when 0 is out of range.
VIX now pivots at 18, real yield US at 2.1.
