Case contract

Input [size, text]. Case-insensitive, surrounding blanks ignored; "pass" -> "pass". Column letters A..Z skipping I; row numbers count from 1 at the bottom. Return [row_from_top, col] or "invalid".

Go servers and scoring tools compute this value automatically; a wrong answer changes a game result.
