CPU opponents now plan more effectively for larger clears and falling-panel chains.

Difficulty improvements

• Easy: Slower play focused on simpler clears.
  
• Normal: Occasional setup planning, with the ability to work on available panels during clears.
  
• Hard: More frequent lookahead and a broader search for setup opportunities.
  
• Super Hard: Fast reactions, planning up to two swaps ahead, and consistent chain forecasting.
  

More active, varied opponents

• Reduced unnecessary pauses on higher difficulties.
  
• CPU opponents independently choose among similarly strong moves, reducing repetitive play.
  
• All CPU actions continue to follow the same legal cursor and swap rules as player actions.
  

These changes apply to CPU opponents. Online player-versus-player rules, ranked records, purchases, and save formats are unchanged.
