Upload an external board image, confirm the FEN, then load into a review session (not mid-game overwrite). Chess is the primary path. Xiangqi: confirm carefully (recognition less reliable). Shogi: hands are inferred from board inventory (heuristic).

How it works
- Pick a game: Chess, Xiangqi, or Shogi.
- Pick a mode: Human vs Human, Human vs AI, or AI vs AI.
- Human vs AI: choose AI strength, move on the board (or type a command), then Fairy-Stockfish replies. Chess has an extra NNUE strength (neural eval); Xiangqi and Shogi do not. AI vs AI: choose strength for each side, set how many games to run, then start the match — Fairy-Stockfish plays both sides.
- After moves, notes, estimated win chance, and coach text update (Ollama when available; otherwise a simple fallback).
Optional: import a board diagram (confirm before load), paste a move list, use the clock, or Preview mode to try one what-if move without changing the live game.
