Conflicts appear when the system cannot safely determine whether an Excel row belongs to an existing player or represents a new one.
No automatic assumptions are made.

• 🟢 Use Existing — The Excel row refers to an existing player, but you do not trust the name or power in this upload.
  Identity is linked only. Name and power remain unchanged.
• 🟡 Rename Existing — Same player, and you trust the Excel data.
  Player name will be updated and power will be overwritten. Identity remains the same.
• 🔵 Create New — The Excel row represents a different player.
  A new player and a new identity will be created. Existing players are untouched.
• ⚫ Ignore — You are not confident enough to act.
  No data changes. Conflict is marked resolved for now.

Important: Always select a player (radio or search) before using any action except Ignore.

Power sanity: Candidates are filtered using realistic growth over time to prevent accidental mismatches.
