/**
 * AgentAvatarMesh — entity-generic procedural humanoid skinned mesh, as PURE DATA.
 *
 * Generalised from the Brittney-locked `studio/.../BrittneyAvatarMesh.tsx` (D.094: the
 * body is entity-generic, parameterised by id; default Brittney, never hardcoded). Unlike
 * that React/Three.js component, this is the sovereign native path: it emits flat vertex
 * arrays + per-vertex skin bindings (NO Three.js, NO GPU) that the native WebGPU character
 * renderer uploads and skins on-GPU. It is the always-works default body source; a glTF/VRM
 * upgrade is a separate, opt-in path (plan: "Both body sources").
 *
 * Geometry: compatibility bodies use one oriented box per skeletal segment. Source-authored
 * bodies can replace the axial torso, shoulder roots, and neck with one connected elliptical
 * loft while retaining the sovereign `HUMANOID_65_SKELETON` skinning path. Each vertex stays
 * rigidly bound to one canonical bone, so the native GPU palette poses the entire figure
 * without an imported body asset or provider runtime.
 *
 * @module character-render
