Module naming 

File-naming helpers that need neither a filesystem nor a random id. File-naming helpers every save path shares.

Reading an extension and appending one when a name lacks it are pure string operations, so they are compiled on every target — unlike the saves that write a file, which need a filesystem and a random id.

Re-exports
