# Copper

Cu cells (40 × 40 × 40 Å) in three disorder regimes (amorphous,
MRO, nanocrystalline) built with
`Supercell.generate(refine_orientations=True)`.

## Static vs refined

Top row is `Supercell.generate()` with the static-relaxation pipeline
only (FIRE quench, no orientation search); bottom row is the same
cell with `refine_orientations=True` enabled. The SO(3) coordinate
search that aligns each grain's lattice to its local environment
before the same final FIRE quench runs.  Drag any panel to orbit;
all six rotate in sync.

## g(r) overlay: static vs refined, all 6 cases

Six g(r) curves on a single radial axis: each regime's static and
refined post-FIRE state, overlaid for direct comparison.
