about

nx_skeleton.nx -- SKELETON + LINEAR-BLEND SKINNING (the character-foundation rung everything Elara needs hangs off: morphs, IK, jiggle-region binding, posing -- VAMX ladder R3, rides nx_mesh3 + nx_itrig per the reuse law). BONES ARE DATA: a rig is rows {parent, local offset, yaw, pitch} a mod can ship. World pose = parent-composed integer 3x3 rotations (fx256) + offsets (fx256). Skinned vertex = sum of per-bone weighted transforms of the vertex's BONE-LOCAL position (LBS with 2 influences, weights fx256 summing 256). ALL INTEGER => deterministic, VM-vettable, wasm-ready (base-relative). license_tier: ORIGINAL
