Pulls every atomic game from your chess.com archives via the public API. Dedup is by timestamp, so it's safe to run repeatedly. Use Wipe & resync if your existing rows have inconsistent timestamps (e.g. a mix of paste-uploaded local-time games and API UTC games) and you want a clean slate.
Upload new games (paste)
Enter the password, paste one or more game blocks exactly as copied from chess.com, and submit. Duplicates (same timestamp) are skipped server-side. The page reloads after upload so stats reflect the new data.
