Documentation could not be built

The documentation build for this version ran and did not produce anything usable. That is usually a shard that does not compile against the Crystal version it declared.

Last attempt Aug 15, 2026 at 17:56 UTC (attempt 2)

Reloading will not start another build. A failed version is left alone for an hour before it can be requested again, so one shard that cannot build does not crowd out the ones that can.
