Process-global ActiveSupport::Inflector state, not scoped to this gem — requiring it inside a real host app (mozo-backend) broke Zeitwerk autoloading of anything with "Api" in its name (JsonApiRenderer camelized to JsonAPIRenderer instead, an uninitialized-constant error with no obvious connection to this gem). Not needed here anyway: autoload_default only ever goes constant name -> file path via #underscore, never the reverse, so this module's own naming never depended on it.
