//! Watertight, chord-tolerance-driven BREP tessellation.
//!
//! The classic per-face tessellator samples every face independently, so
//! adjacent faces disagree along their shared edge and the mesh has cracks.
//! Here every EDGE is sampled once — adaptively, until the 3D chord sag is
//! below the chord tolerance — and both adjacent faces consume the exact
//! same sample positions (endpoints come from the shared vertex records), so
//! coincidence along shared edges holds bit-for-bit by construction.  Each
//! face is then triangulated in parameter space: trim loops built from the
//! shared samples (holes bridged to the outer loop), ear clipping, then
//! conforming interior-edge splits until interior chords also meet the
//! tolerance.  Boundary edges are never split, so no T-junctions can appear.
