/**
 * Keys whose VALUES are user-authored data, never schema. Both converters copy
 * the value through untouched instead of recursing: a script-exported variable,
 * a `metadata/<key>`, or a shader uniform (`shader_parameter/glowAmount`) is an
 * identifier the user chose, and rewriting its case corrupts it. The keys
 * themselves are still converted like any other key.
 *
 * `properties` - add_node property dict (standalone and batch).
 * `value`      - set_node_properties update value (standalone and batch).
 *
 * Neither name is ever a structural key in the params a handler builds, so the
 * match is safe position-independently. Adding a name here is a contract change:
 * everything under it stops being case-converted in both directions.
