Struct PackedExtField 

pub struct PackedExtField<F: Field, PF: PackedField<Scalar = F>, const D: usize, Shape> { /* private fields */ }

Unified packed extension-field representation (SIMD-lane parallel).

PackedExtField<F, PF, D, Shape> stores D packed coefficients (one per SIMD lane), representing the WIDTH extension-field elements that fit in one SIMD register simultaneously.

The three public-facing packed types — PackedBinomialExtensionField, PackedCubicTrinomialExtensionField, PackedQuinticTrinomialExtensionField — are type aliases over this struct with their respective Shapes.
