## FOITIN content editor — the "secondary app", built in.
## - edit fighter names/stats/colors -> saved to user://overrides/<id>.json
## - import a character folder (pack_character output) -> user://characters/
## - add stage background images -> user://stages/
## Everything it writes lives in user:// so it works from the shipped app;
## the game merges overrides and scans user:// folders at load.
