Private leagues need your ESPN session: DevTools → Application → Cookies → fantasy.espn.com. Paste SWID with braces and espn_s2 exactly as stored. Only the server ever sees them.

Your own rankings or a manually prepared PFF-derived file. Columns are detected (rank, player, position, team, tier, notes). Unmatched names are listed with suggestions.

1. chrome://extensions → Developer mode → Load unpacked → the extension folder.
2. Pin it, click the icon (or right-click → Options): App URL …, and your token. Save tests the connection. The draft room is detected automatically — real league, lobby mock or practice draft — no league id to enter.
3. Open the ESPN draft room in that same Chrome window. Badge ON = capturing. Draft from that window; use the phone only for this app.
