name: 'Free disk space on hosted runners'
description: |
  Aggressively clean GitHub-hosted ubuntu-latest runners to reclaim ~6-10 GB
  of working space before docker buildx steps. Combines jlumbroso/free-disk-space
  with explicit apt purges of large packages we never use (dotnet, ghc, mono,
  android, jdk, ...).

  No-op on self-hosted runners; pass mode=skip to force-disable.

inputs:
  mode:

    default: 'hosted'
