Additional information

Also, if I may say, "raw" is not the correct word here. One would expect that to represent a pure version, unchanged by Lichess, something like the original text of the imported PGN perhaps or something like that. Perhaps something like "clean" or "plain" or "stripped" would work better. People have been demanding strip chess for a long time!
