1. Missing noreferrer on link 🐞 Bug ⛨ Security

Description

The new blog card opens a third-party site with target="_blank" but uses rel="noopener" only, so
the browser can still send a Referer header to the external site. This is inconsistent with the
project’s navbar external-link handling (rel="noopener noreferrer") and can cause unintended
referrer leakage.

Code

layouts/blog/list.html[R144-146]

+        <a href="https://developers.redhat.com/articles/2026/06/04/type-what-you-want-break-ai-assisted-chaos-engineering-krkn" target="_blank" rel="noopener"
+           class="krkn-blog__card"
+           data-category="ai" data-type="article">

Evidence

The added blog card uses target="_blank" with rel="noopener" only, while the navbar shows the
intended convention for external links is rel="noopener noreferrer".

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
A newly added external link uses `target="_blank"` with `rel="noopener"` only. This does not suppress the Referer header and is inconsistent with other parts of the site that use `rel="noopener noreferrer"` for external links.

### Issue Context
The navbar template already applies `rel="noopener noreferrer"` for external `http` links, indicating a project convention.

### Fix Focus Areas
- layouts/blog/list.html[144-146]

### Suggested change
Update the anchor to:
```html
rel="noopener noreferrer"
```
(Optionally consider applying the same change to the other external blog cards for consistency.)

I dont think so it is related to my code changes, as it is simple HTML addition

Hi @ddjain! 👋 One or more commits in this PR are missing a Signed-off-by line, which is required by our DCO policy.

Unsigned commits:

• d8e515c: Merge branch 'main' into add-krkn-skill-blog-entry

To fix, rebase and sign off all commits:

git rebase HEAD~1 --signoff
git push --force-with-lease

Or, to sign off every commit in this PR at once:

git rebase origin/main --signoff
git push --force-with-lease

Tip: Add -s to future git commit commands (e.g. git commit -s -m "...") to sign off automatically.

Note: Please make sure your PR contains only 1 commit before signing off. If you have multiple commits, squash them first:

git checkout <my-working-branch>
git rebase -i HEAD~<num_of_commits_to_merge>
   -OR-
git rebase -i <commit_id_of_first_change_commit>

In the interactive rebase screen, set the first commit to pick and all others to squash. Then push your rebased commits:

git push origin <my-working-branch> --force-with-lease

See the Squash Commits guide for more details.

The needs-dco label and this comment will be removed automatically once all commits are signed off.
