Installing Packages

When adding a new dependency to any package.json in the monorepo:

Look up the latest version on npm before adding:
```
pnpm view <package-name> version
```
If unsure which version to use (e.g. major version compatibility), confirm with the user.
Edit the package.json directly — do NOT use pnpm add as it can cause issues in the monorepo. Add the dependency with the correct version range (typically ^x.y.z).
Run pnpm i from the repo root after editing to install and update the lockfile:
```
pnpm i
```
Always run from the repo root, not from the package directory.
