summary: In GLD display mode, show real GLD share prices without conversion to physical gold.
acceptance_criteria:
  - GLD mode shows position quantity as "shares" not "oz"
  - GLD mode shows position value as `shares × GLD_price` not converted to gold
  - Entry price shown as GLD share price at time of purchase
  - P&L calculated as `(current_GLD_price - entry_GLD_price) × shares`
  - LTV calculated using GLD position value as collateral
  - Options strike selection in GLD mode uses GLD share prices directly
  - Hedge cost shown as $/share or $/position, not $/oz
implementation_notes:
  - Added `display_mode` field to PortfolioConfig (default: "XAU")
  - Created app/domain/conversions.py for display mode conversion utilities
  - Updated portfolio_math.py to respect display_mode in spot resolution and snapshots
  - Updated overview.py to show share prices/units in GLD mode
  - Updated hedge.py to show share prices/units in GLD mode
  - Updated settings.py to allow display mode selection
  - Added tests/test_display_mode.py with comprehensive test coverage
  - Default display mode remains "XAU" to preserve existing behavior
  - GLD mode short-circuits conversion logic, showing share prices directly
