A GPU or large runner is used but no compute-intensive steps (model training, heavy compilation) are present.

Detection

``pattern_matching`` — Regex or keyword matching on string field values.

Examples
--------

**Non-compliant:**

.. code-block:: yaml

   jobs:
     lint:
       runs-on: ubuntu-latest-gpu
       steps:
         - uses: actions/checkout@v4
         - run: npm run lint

**Compliant:**

.. code-block:: yaml

   jobs:
     lint:
       runs-on: ubuntu-latest
       steps:
         - uses: actions/checkout@v4
         - run: npm run lint

**Fix**: Replace the GPU or large runner with a standard runner (ubuntu-latest) for lightweight tasks. Reserve large runners for compute-intensive workloads like model training or heavy compilation.
