//! `indicatrix` is a physically-based spectral gemstone renderer.
//!
//! Turns GemCAD-style cutting schedules (facet angles and index positions)
//! into rendered output: spectral analytical / Monte-Carlo raytracing through
//! faceted gemstone geometry, plus brilliance / fire / scintillation metrics.
//!
//! No UI toolkit or data-source dependency: callers supply plain
//! [`FacetSpec`] rows (or hand-built [`geometry::GpuFacetPlane`] sets) and a
//! [`optics::materials::GemMaterial`], and get back pixels and/or metrics.

// `wgpu`'s type nesting overflows the default recursion limit when proving
// `Send` for the closure `renderer::gpu::hybrid` spawns onto a scoped thread.
// 256 clears current nesting with headroom; raise only if a future `wgpu`
// upgrade nests deeper.
#![recursion_limit = "256"]

/// must refuse to combine samples unless builds match, since differing
