RTD build/deployment has not been triggered for over 2 months

Describe the issue/behavior that seems buggy

Read the Docs has not built or updated the highlight.js docs for over 2 months. The page shows no changes, and the project has no recent builds.

• Project: https://app.readthedocs.org/projects/highlightjs/
• Page: https://highlightjs.readthedocs.io/

Sample Code or Instructions to Reproduce

1. Open the RTD builds page: https://app.readthedocs.org/projects/highlightjs/builds/
2. Check for any build triggered after PR #4433 was merged.
3. Visit https://highlightjs.readthedocs.io/ and verify whether the docs reflect PR #4433.

Expected behavior

Merging PR #4433 into main should trigger an RTD build and deploy the updated docs (e.g., the shibuya theme). A new build should appear, and the page should update.

Additional context

As we can see, the latest version has not been updated for almost 2 months and 3 weeks as of today (2026/9/14):
