/* ----------- Usage Instructions -------------- */
/*
    To use the pixel art base:
    - Add the class 'crt' to any container to apply a CRT effect (e.g., a large pixel art section or an entire page).
    - Use the class 'button-pixel' for any button to give it a rounded, retro look.
    - The 'sprite' class applies to elements using sprite animations; you can customize the background image and animation steps for your sprites.
    - Use the 'container-pixel' class for responsive pixel art grid layouts.
    - Use the 'bg-pixel' class for tiled pixelated backgrounds.
    - Add '.pixelated' to images to prevent smoothing and make them appear pixelated.
