// Module-level Key enum class (created at runtime using Python's IntEnum)
// Stored as a module attribute: mcrfpy.Key
//
// Values map to sf::Keyboard::Key enum values.
// The enum compares equal to both its name ("ESCAPE") and legacy string ("Escape")
//
// Naming convention:
// - Letters: A, B, C, ... Z
// - Numbers: NUM_0, NUM_1, ... NUM_9 (top row)
// - Numpad: NUMPAD_0, NUMPAD_1, ... NUMPAD_9
// - Function keys: F1, F2, ... F15
// - Modifiers: LEFT_SHIFT, RIGHT_SHIFT, LEFT_CONTROL, RIGHT_CONTROL, etc.
// - Navigation: LEFT, RIGHT, UP, DOWN, HOME, END, PAGE_UP, PAGE_DOWN
// - Special: ESCAPE, ENTER, SPACE, TAB, BACKSPACE, DELETE, INSERT, PAUSE
