## Description

Change-case is a software library that provides text formatting, character case inversion, and naming convention normalization across codebases. It converts strings between standard naming formats such as camelCase, snake_case, PascalCase, and kebab-case using customizable delimiters and locales. 

The library implements isolated casing converters, functional transformation pipelines, and regular-expression-based tokenisation to split input strings into discrete word tokens. It includes utilities for formatting text into title case, inverting character cases, swapping letter capitalization, and applying random capitalization. Additionally, it supports recursive object tree traversal to uniformly transform object keys across nested data structures.
