Classes
struct	peclet::core::amr::CsrCountSink
	Sink passed to the emit functor during the COUNT pass: just tallies faces. More...
struct	peclet::core::amr::CsrFillSink
	Sink passed to the emit functor during the FILL pass: writes each face into the cell's own slice [start_i, start_{i+1}) at the running cursor k (no atomics — deterministic). More...
struct	peclet::core::amr::Csr
	An assembled face-CSR: row offsets (size n+1), neighbour index + coefficient per face (size nFaces). More...

Functions
template<class CountFn >
View< Index >	peclet::core::amr::scanOffsets (Index n, const CountFn &countFn, Index &nTotal)
	CSR row offsets (size n+1) from a per-cell count functor, via one exclusive prefix scan, with the total written to nTotal.
template<class Emit >
Csr	peclet::core::amr::buildFaceCsr (Index n, const Emit &emit)
	Build a face-CSR on device from a per-cell emit functor.
