Detailed Description

Portable mirror of ShapeDescriptor (analytic fields + a flat-array point shell).

For an imported grid SDF (type == SHAPE_GRID_SDF) the analytic params is unused except params.x, which carries the canonical bounding radius (used by the broad-phase splat / VTI export). The signed-distance samples live in the shared Particles::sdfGrid View at [gridOffset, gridOffset + nx*ny*nz), x-fastest (idx = x + y*nx + z*nx*ny), located at the regular lattice nodes q = gridOrigin + (x,y,z) / gridInvSpacing in canonical (unrotated, unit-scale) particle space. Analytic shapes leave these zero.
