DuoChess v1.1.0 — Changelog

Solver (lesson)

• Add Turbo mode (default ON) — the move is sure to be correct, so remove the canvas verification, just keep the minimum delay enough to click (60ms press / 60ms gap / 90ms settle)
• Enemy move still polls for real (server decides), but polling is faster (10ms interval)
• Hash canvas sample area 32×32 instead of 64×64 → check faster
• Toggle ⚡ Turbo in the Solver tab, you can turn it off to fallback verify-wait like the old version

Detect chessboard

• Cache canvas 150ms, avoid constantly rescanning the DOM
• Filter out canvases with pointer-events:none (avoid mistaken effect/confetti layers)
• Cache automatically invalidates when the board is actually changed, do not use the old coordinates after remounting

Bot (fight Oscar)

• Fix race condition: snapshot FEN at the beginning of thinking, validate again with chess.js if the board changes while the engine calculates the move — avoid going against the rules/wrong pieces when the Stockfish API responds slowly
