"""Generate synthetic DICOM fixtures for dicom_series_preflight.

  clean_no_phi/  — canonical pass (LPS CT, no populated PHI tags)
  clean_axial/   — warn demo (same geometry, PHI tags populated)
  flipped_lr/    — fail demo (LR-flipped IOP)

Reuses the same volume geometry as dicom_series_to_volume fixtures.
