⚡ Rchess rules

• ♜ All 16 pieces random on 1st+2nd rank
• 🔴 Back‑rank pawn (marked ¹) → only 1 square
• ✅ Other pawns: 1 or 2 squares first move
• 👑 KING SAFETY — if king started on 2nd rank and is in check, ANY piece can block/escape on the very first reaction (ignoring pins). This “first pass” works only once per game.
• 🚫 No castling
