Task: a single Python file whose title/description stress indentation and whitespace; visible source is a decoy flag-format checker. Solution: each line carries 8 trailing space/tab characters encoding 8 bits (space=0, tab=1); decode bytes to recover the flag, after splitting on CRLF to avoid the trailing-\\r pitfall.
