constants.py - Roguelike Template Constants

This module defines all the constants used throughout the roguelike template,
including sprite indices for CP437 tileset, colors for FOV system, and
game configuration values.

CP437 is the classic IBM PC character set commonly used in traditional roguelikes.
The sprite indices correspond to ASCII character codes in a CP437 tileset.
