[bug\_fix] npm WARN ERESOLVE overriding peer dependency; npm WARN Found: [email protected]; npm WARN Could not resolve dependency: react@"^17.0.0"

Install an explicit, compatible version of the peer dependency at the top level \(\`npm install react@17 react-dom@17\`\), or downgrade the package that is pulling the newer peer, or use \`--legacy-peer-deps\` / \`--force\` with caution. The root cause is that a package expects a peer it does not itself install; npm warns because the version at the top of the tree does not satisfy the peer range.

Journey Context:
You add \`@storybook/react\` to a fresh React 18 project and the terminal fills with peer-dependency warnings. The app still starts, but Storybook's internal addons throw invariant errors about mismatched React versions at runtime. You check \`npm ls react\` and find Storybook expecting React 16 \|\| 17 while your app uses 18. The rabbit hole leads through \`.storybook/main.js\`, then to Storybook's package.json \`peerDependencies\`. The cleanest fix is upgrading Storybook to a version whose peer range includes React 18. When that is not yet possible, you temporarily install React 17 as an explicit dependency and alias it in bundler config. You learn peer deps are a contract: ignoring the warning shifts the breakage to runtime.
