How $1000 moves through an Event Card — Timeline
Deposit → credit → buy a real basket → mark to its live NAV → settle → withdraw. Built on a real, live event card; the index chart is live data.

Live basket index (5d) — what the marked-to-NAV value tracks
Position math mirrors the real engine: units = basket_cost / entry_index,
value = units × current_index (see trading_service.open_bull_position).
Items tagged illustrative (slippage, gas) are real costs
that are baked into per-leg execution and not exposed on any API, so they're shown as labeled constants.
