// humanoid-chibi.js — 分件人形「大头 chibi」骨架（RigDefinition）。
// 移植自旧原型 client/js/stage/rig/humanoid-chibi.js（注册名 humanoid_parts，全角色实际使用的就是它）。
//
// 与 humanoid_v1 的关键差异：这是按真实角色立绘（worker/lady 等，画布 454×750）调好骨距的骨架——
// neck 距 torso -273、head -30、face -120、upper_arm 85/-235、shin 间距 130。worker/lady 的部件对齐
// 数值（anchor/bonePos/scale）全部按本骨架的 setup-pose 调出，故角色必须绑本骨架而非 humanoid_v1，
// 否则骨距不符会把身体压扁、头显得过大（实测过的坑）。
//
// 坐标系：+y 向下，角度「度」；root 在双脚之间贴地（y=0），身体向上为负 y。bones 顺序父先于子。
