There are some security issue(s) on this PR. I will fix it them and merge PR.

It appears that image-size, which docusaurus depends on, has a security issue, and there is no fix available yet.

This problem persists even after updating docusaurus to the latest version, so I will update it immediately once a version with this issue resolved is released.

The failing build check is unrelated to this PR. The build itself succeeds — it is the following npm audit --audit-level=high step that fails, due to an unpatched CVE in image-size (GHSA-w3rx-r6r6-pgpr) pulled in via @docusaurus/mdx-loader. Every PR opened right now fails the same way. It is not a required status check, so merging is unaffected — leaving it red until we address it in a separate PR.

This PR is approved and mergeable as is, so go ahead and merge it.

Follow-up: #29 fixes this at the source — it raises the overrides for the two fixable advisories and allowlists the two unpatchable image-size ones. Its own build check is green.

Note that merging #29 will not turn this PR green on its own: a pull_request workflow is not re-triggered by base branch updates. Rebase this branch after #29 lands and the check will pass — or merge as-is, since the check is not required either way.
