useFormatters().price() now accepts an optional sourceCurrency param. When showConversions is enabled and the source differs from the user's currency, it converts via ECB rates and shows dual format: "€200.00 (~$218.00)". ItemCard and CollectionView pass priceCurrency through from API data. Setup detail items also pass priceCurrency. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
