description: |
  Build, sign, and publish release binaries for a Vikunja sub-project.

  Derives every per-project path, cache key, artifact name, and S3 target
  from the `project` input. Callers only need to provide the project name,
  the raw `git describe` value, and pass through the GPG/S3 secrets as
  inputs (composite actions can't read `${{ secrets.* }}` directly).  

inputs:
  project:
    description: 'Which project to build: "vikunja" or "veans".'
    required: true
  release-version:
    description: 'Raw git describe value (e.g. v1.2.3 or a sha). Use "" or "main" for unstable builds.'
    required: true
  # Secrets — composite actions can't read `${{ secrets.* }}` directly, so the
  # caller threads them through as inputs.
