Highlights

• Refined the field into micro-pixel Braille art for a larger 14-by-8 tile view while retaining an 80-by-24 terminal layout.
• Added an optional locally synthesized chiptune BGM with a persistent preference and in-game toggle.
• Kept custom companion sprites compatible with older 7-by-6 saves; new pets use the more detailed 8-by-8 canvas.
