AnsiOutput class

A utility class for formatting terminal output using ANSI colors and background styles.

This class provides static helper methods to apply foreground or background ANSI styles to any string, making console logs more readable and expressive.

βœ… Example Usage:

print(AnsiOutput.green("βœ” Success"));
print(AnsiOutput.red("βœ– Error"));
print(AnsiOutput.onRed("πŸ”₯ CRITICAL"));
print(AnsiOutput.onYellow("⚠ Warning", AnsiColor.BLACK));

You can also manually apply styles with:

print(AnsiOutput.apply(AnsiColor.BOLD, "Important!"));

Typically used in CLI tools, startup banners, or colored logging.
