name: Build

# Skip the build when only documentation / metadata files change.
# `paths-ignore` evaluates per file: if EVERY changed file matches the list,
# the workflow is not started; any non-matching file forces the full build.
# `workflow_dispatch` is not affected and can always force a manual run.
#
# CAVEAT - required status checks: if a branch-protection rule on `master`
# ever requires the "Build" check to report on every PR, doc-only PRs will
# become un-mergeable because no run is created and no check is posted.
# In that case, switch from `paths-ignore` to a `dorny/paths-filter` step
# that gates each build step with `if:`, so the workflow always starts and
# reports a green check even on doc-only changes.
# (Required status check = a check name listed in Settings -> Branches ->
#  -> Branch protection rules -> Require status checks to pass before merging.)
