-name: Resolve buildx cache settings
-description: >-
-  Turns the DOCKER_CACHE_* variables exported by the runner into buildx driver options and
-  cache refs. Missing variables degrade the job to a build without cache instead of failing it.

-inputs:
-  cache-image:
-    description: Cache image path without the registry host (e.g. "org/repo/app").
-    required: true
-
-outputs:
-  driver-opts:
-    description: driver-opts for docker/setup-buildx-action; empty when the cache registry needs no network pinning.
-    value: ${{ steps.resolve.outputs.driver-opts }}
-  cache-from:
-    description: cache-from ref for docker/build-push-action; empty disables cache reads.
-    value: ${{ steps.resolve.outputs.cache-from }}
-  cache-to:
-    description: cache-to ref for docker/build-push-action; empty disables cache writes.
-    value: ${{ steps.resolve.outputs.cache-to }}
