 * Spring bone parameters for a wearable's GLB models.
 *
 * `models` is keyed by GLB content hash (the value found in WearableEntity.content[mainFile]).
 * Hash-keying means a single GLB shared across multiple body-shape representations resolves
 * to one entry, and entries are stable across path renames.
 *
 * - Outer key: GLB content hash.
 * - Inner key: spring bone name as it appears in the GLB.
 *
 * Example:
 * ```
 * {
 *   version: 1,
 *   models: {
 *     "bafkreialsvt77jvpy673cnugp5ggnxfaalfncufweayuk3jbxskh3pelkm": {
 *       "Hair_springBone_L": {
 *         stiffness: 2,
 *         gravityPower: 0.8,
 *         gravityDir: [0, -1, 0],
 *         drag: 0.3,
 *         center: "Avatar_Hips",
 *         isRoot: true
 *       }
 *     }
