## STRICT INSTRUCTIONS - FOLLOW EXACTLY
- Always run `nvm use` first to ensure you are using the correct Node.js version.
- Install Yarn globally with `npm install -g yarn`.
- Verify Yarn version by running `yarn --version`. You must be using Yarn 1.x.
- Do NOT run `yarn install` if the `node_modules` directory already exists. The dependencies are already installed.
- If you encounter `Failed to replace env in config: ${NPM_TOKEN}`, set a dummy token with `export NPM_TOKEN=dummy` in the shell.
- Set environment variables as defined in `.circleci/config.yml`:
    - Check if each variable is already set in the shell environment.
    - Only set variables that are missing by reading the `environment` section in `.circleci/config.yml`.
    - Do not override existing shell environment variables.
- When testing changes:
    - Strictly follow the steps in `.circleci/config.yml`.
    - Ignore all `service-deployment/*` jobs.
    - Never rerun `yarn install`—it has already been executed in the setup script.
- If you see this error:
    - `This package doesn't seem to be present in your lockfile; run "yarn install" to update the lockfile at jR.getCandidates (/root/.cache/node/corepack/v1/yarn/4.9.2/yarn.j)`
    - It means you are using the wrong Yarn version.
    - Run `nvm use` again to ensure the correct Node.js version is active.

Follow these instructions exactly. Do not skip or modify any steps.
