## Findings (1)

```yaml
- file: release-notes/elastic-cloud-serverless/breaking-changes.md
line: 9
category: weak-opening
severity: medium
evidence: "No opening paragraph after the H1; the page goes directly from the title
into an HTML comment block and then into dated H2 sections, leaving readers with
no description of what the page covers or why they should read it"

## Done when
- All listed pages have a specific, contextual H1; an opening paragraph that conveys purpose; and (where applicable) a prerequisites section.
- A PR addressing this issue is merged.

## Notes
- The 45 `_snippets/*` files are include fragments (no frontmatter, H2-only, rendered only via `:::include` in parent pages) and were excluded from page-opening analysis.
