Why this form

The complete relevant record is already in this pane; a second map would repeat it.

Detached evidence · not connected to the daily-last curves

intraday low intraday low $329 · Sep 10 2026 · retained from that price-day; not the daily-last curveSource · WTV-EXPORT-00185
dated sighting highest witnessed $440.00 · Mar 10 2026 · dated sighting — not from our day-by-day recordSource · WTV-STATS-HIGH-20260310

Every line uses reduced price-days for one exact retailer offer. Both series share the coverage mask; intraday and Class B facts remain detached marks. The receipt ledger below is the complete text alternative.
