📝 Walkthrough

Walkthrough

The pull request tightens dependency version constraints in package.json by replacing caret-based semver ranges with exact version pins for multiple packages (Docusaurus, React, ReactDOM, and related tools) and raises the Node.js engine requirement from >=18.0 to >=20.0.

Changes

Cohort / File(s)	Summary
Package Configuration package.json	Pinned exact versions for 9 dependencies (@docusaurus/core, @docusaurus/preset-classic, @docusaurus/theme-mermaid, @mdx-js/react, @easyops-cn/docusaurus-search-local, by-node-env, clsx, react, react-dom, yaml-loader) by removing caret (^) ranges.
