## Done when
- Stale content has been refreshed, archived, or annotated as historical.
- Stale screenshots are re-captured.
- Broken external links are replaced with current sources.
- Unsupported-version mentions are removed or moved to upgrade docs.
- A PR addressing this issue is merged.

## Notes
- No stale-content pages found in this shard (all 146 in-scope pages are under the 24-month threshold).
- No unsupported-version-mention findings: version references in scope pages are either minimum-version requirements, upgrade-context notes, or release notes (legitimately referencing older versions).
- `bear.png` in `syntax-quick-reference.md` is a placeholder/illustration image (not a UI screenshot) and was excluded from stale-screenshot findings.
- Timeout on `https://azure.microsoft.com/en-gb/documentation/articles/storage-premium-storage excluded (transient failure, not a confirmed 404).
- Private GitHub repo links (`github.com/elastic/autoops`, `github.com/elastic/cloud`) excluded — 404 is expected without authentication.
