The **theming** package provides a lightweight, React‑specific solution for managing CSS‑in‑JS themes. It supplies a `ThemeProvider` that injects, merges and updates a theme via React context, a `withTheme` HOC (and a `useTheme` hook) to give components easy access to the current theme, and a `createTheming` API for integrating custom context into other CSS‑in‑JS libraries. It’s aimed at React developers who want a simple, isolated way to apply and share design tokens across their component trees.
