Functions
void	peclet::core::amr::restrictField (View< const Index > childStart, View< const Index > childIdx, View< const double > fine, View< double > coarse, Index nCoarse)
	Restrict: coarse(p) = mean over p's children (CSR fixed order ⇒ deterministic).
void	peclet::core::amr::restrictKappa (View< const Index > childStart, View< const Index > childIdx, View< const double > fine, View< const double > kappa, View< double > coarse, Index nCoarse)
	Restrict, κ-weighted: coarse(p) = Σ_child κ_c·fine_c / Σ_child κ_c, with κ the fine cell's fluid-fraction weight (mean face aperture).
void	peclet::core::amr::prolongAdd (View< const Index > c2p, View< const double > coarse, View< double > fine, Index nFine)
	Prolong (piecewise-constant) + correct: fine(i) += coarse(c2p(i)).
void	peclet::core::amr::prolongAddMasked (View< const Index > c2p, View< const double > coarse, View< const char > excl, View< double > fine, Index nFine)
	Masked piecewise-constant prolong + correct: fine(i) += coarse(c2p(i)) only on non-excluded fine cells (mirrors flow VelocityMG::prolongMasked — no correction into a cut/solid cell).
void	peclet::core::amr::zeroMasked (View< double > v, View< const char > excl, Index n)
	Zero v at excluded cells (excl != 0).
