To Remove

Items present in the "have" fit but not in the "want" fit (or in excess quantity).

Shared Items

Collapsible section showing items common to both fits (identical name and quantity).

Hull Mismatch Warning

If the two fits use different ship hulls, a warning alert is shown.

EFT Format

The parser expects standard EFT (EVE Fitting Tool) format:

Blank lines separate slot groups. Ammo/charges in square brackets after modules are parsed. Quantities use xN suffix.
