QuectoColors class final

Nesting-aware ANSI stylers with single-pass ESC byte scanning.

Unlike QuectoPlain, these stylers detect nested ANSI close codes within the input and re-inject the parent style's open code after each close, ensuring correct color nesting.

print(QuectoColors.red('Hello ${QuectoColors.blue('world')} !'));

Static Methods

ansi256(int code) → QuectoStyler

Sets foreground to xterm 256-color palette index code (0–255).
