CI may not have run on this PR. Without a SPEC_SYNC_TOKEN secret it is opened
with the default GITHUB_TOKEN, which cannot trigger workflows — so api-client-drift,
build and the rest stay silent. Close and reopen the PR (or push an empty commit) to
run them. The compile check above is a preview, not a substitute.
