Overview

Lightweight ANSI color/style wrapper with chainable style methods. Wrap a string with NextRails::Tint("text") then chain styles:

NextRails::Tint("hello").red.bold

Instances are effectively immutable: each style method returns a new Tint rather than mutating the receiver, so a reference can be reused without styles accumulating across chains.
