+summary: Apply explicit instrument-aware quote-unit conversions to the next visible ounce-based hedge/runtime paths so they no longer assume ounce-native spot prices.
+acceptance_criteria:
+  - Hedge/runtime displays that consume live or configured GLD spots use explicit share->ozt conversions where needed.
+  - Visible strategy/hedge labels distinguish converted collateral spot from raw share quotes when relevant.
+  - Unsupported or missing quote-unit metadata fails closed rather than silently applying raw share prices as ounce prices.
+  - Tests cover the changed hedge/runtime math and browser-visible route behavior.
+technical_notes:
+  - Likely file targets include `app/pages/hedge.py`, `app/pages/common.py`, and any service/helpers feeding hedge summary/runtime spot values.
+  - Reuse the new instrument metadata seam rather than introducing new ad hoc scale factors.
+  - Keep backtesting/event share-based paths compatible while tightening visible ounce-based paths.
