Detailed Description

The destination side of a tiled copy — the packed local buffer — as a (possibly swizzled) Layout over the coordinate [slot ++ tile].

The buffer is a staging area [per-thread slot dims][per-slot tile block]. Two independent choices shape it: the Placement orders the tile axes (an affine relabelling), and the ConflictPolicy spreads accesses over memory banks (padding or an XOR swizzle) — see the module README.
