Explanation

To run multiple shell commands in a single step, use the run: key with the block scalar indicator | (pipe), which preserves newlines and allows multi-line commands:

- run: |
    npm ci
    npm run build

The | character is YAML syntax for a literal block scalar, treating each line as a separate command. Options using shell: (B, E) are not valid GitHub Actions step keys for running commands - shell: is a sub-key of run: to specify the shell type, not a standalone key. Option D (- run: without |) would only support a single inline command, not multiple lines.
