If data/backlinks.json fails to parse, every page that uses the
backlinks context aborts with 'fail'. The JSON is build-generated;
corruption is unlikely but not impossible (interrupted writer, disk
issue). Switch to noResult so the affected pages render without the
backlinks block instead of failing the whole build. The next clean
build regenerates the JSON.
Note: commonplace.yaml and now.yaml deliberately keep fail-fast —
they're hand-edited and silent fallbacks would mask author typos.
