Functions
std::expected< std::vector< SphericalHarmonicMode >, DeformationFailure >	serif::geometry::deformation::detail::make_harmonic_modes (const SphericalHarmonicSurface &model, std::size_t node_count)
	Validate harmonic cutoffs before allocating a basis or enumerating modes.
std::expected< std::vector< double >, DeformationFailure >	serif::geometry::deformation::detail::sample_harmonic_basis (const SphericalHarmonicSurface &model, std::span< const SphericalHarmonicMode > modes, std::span< const std::array< double, 3 > > directions)
	Use normalized Legendre recurrence to avoid factorial growth while preserving the Condon–Shortley phase.
DeformationStatus	serif::geometry::deformation::detail::check_independent_harmonics (std::span< const double > basis, std::size_t node_count, std::size_t mode_count)
	Check sampled rank on a private copy, leaving physical coefficients and basis normalization unchanged.
