How juanp95m/cub3d_public works

Cub3D is a raycasting game that accepts a .cub map, validates its configuration and walkable map, initializes graphics, and runs an interactive movement-and-render loop. Its main domain stages are parsing, map validation, player control, raycasting, and drawing. MLX42 supplies the graphics runtime; libft and get_next_line provide supporting utilities. Several internal calls are not visible in the excerpts, so links beyond the main entry point and README-documented behavior are omitted or marked unverified.
