      timeout-minutes:
        description: >-
          Timeout for the test step alone. Setup (checkout, dependency install,
          Prisma client generation) gets its own allowance on top, so a slow
          runner or a cold binary download can never cancel passing tests.
        required: false

        default: 20
      job-timeout-minutes:
        description: >-
          Backstop for the whole job. Keep it >= `timeout-minutes` plus 35: 30 for
          the per-step ceilings on the setup steps below, and 5 for the runner
          overhead the job clock charges but no step owns (job init, step
          transitions, post-job cleanup). That headroom is what makes the test
          budget a floor rather than a hope, since setup cannot overrun into it
          without failing its own step first. GitHub expressions have no
          arithmetic, so the sum is passed in rather than computed.
