Back sprites:
  Exact per-file source and credit are recorded in RUNTIME-MANIFEST.json.
  The selected set includes credited PeanutellaXO contributions, a separately
  documented Volcanion composition pilot, and mechanically reduced PokeAPI
  reference candidates. Mechanically reduced backs still require visible
  manual quality review before they may be called final artwork.

Excluded:
  Mega forms and Gorochu are not part of this library. The quarantined
  SageDeoxys package was not copied, read as an image reference, or used as
  generation input because its supplied terms prohibit AI use.

Pokémon and official designs belong to their respective rights holders.
