Description

This PR fixes #8344

In src/collections/news/2026/2026-01-21-docker-kanvas-kubernetes-dominance/index.mdx, darkthumbnail was pointing to ./docker-kanvas-infoq.png, which does not exist in the directory (the asset was converted to .webp). This updates darkthumbnail to point to ./docker-kanvas-infoq.webp matching thumbnail.

Notes for Reviewers

• Only changes the file extension in darkthumbnail from .png to .webp in src/collections/news/2026/2026-01-21-docker-kanvas-kubernetes-dominance/index.mdx.

Explanation

The title '[News] Fix darkthumbnail image path in Docker Kanvas post' matches the changeset. The only change updates the darkthumbnail metadata in the Docker Kanvas news post from docker-kanvas-infoq.png to docker-kanvas-infoq.webp, which the linked issue #8344 requests.

Full details: Linked Issues check

Explanation

Issue #8344 requires that darkthumbnail in src/collections/news/2026/2026-01-21-docker-kanvas-kubernetes-dominance/index.mdx point to ./docker-kanvas-infoq.webp. The reviewed head changes line 7 from ./docker-kanvas-infoq.png to ./docker-kanvas-infoq.webp, which matches the requirement. The file docker-kanvas-infoq.webp exists in the post directory at the reviewed head, so the reference resolves. The issue does not request automated tests or other coding work. The whole-PR diff against the merge base contains only this one-line change.

Nice catch, and thanks for the clear writeup tying it to #8344.

I verified the fix holds up: docker-kanvas-infoq.webp exists in the article directory, there is no .png by that name left, and darkthumbnail now matches thumbnail, so dark mode will stop pointing at a missing file.

One small check before this lands: could you confirm the dark-mode card for this post renders the thumbnail correctly in a local preview? The frontmatter change itself looks exactly right.

[ayushbuilds-code]

Thanks for the review @miacycle! Confirmed that the thumbnail asset resolves properly with darkthumbnail: ./docker-kanvas-infoq.webp without missing file errors in dark mode. Appreciate the review!

Thanks for confirming the dark-mode render. I re-checked the head commit: the one-line change matches issue #8344 exactly, docker-kanvas-infoq.webp exists in the article directory, there is no .png left, and darkthumbnail now matches thumbnail. Checks are green. Approving.
