The PR description says Node.js 22 is required, but the updated dependency tree now has packages (e.g., Astro/@astrojs/mdx) declaring an engine requirement of >=22.12.0. To avoid confusing install/build failures for contributors using older 22.x (or 20.x), consider updating the PR description and adding an explicit "engines" field in docs/package.json (at least for node) to reflect the minimum supported version.

👋 Thanks for the automated Astro dependency bump! Keeping astro, @primer/octicons, and starlight-llms-txt up-to-date in the docs site is exactly the kind of routine maintenance the project relies on.

One thing worth noting for completeness:

• No test changes — the checklist flagged the absence of test file changes. For a pure lock-file + manifest version bump like this one, that's entirely expected — there's no new logic to cover. The best signal here is CI passing cleanly, which the PR body already confirms (npm run build ✅).

Since this is still a draft, if there are any CI checks pending, confirm they pass before marking it ready for review. Once green, this looks ready to merge.

If you'd like an agent to verify the build and promote this to ready-for-review:

In the gh-aw repository, check PR #27543 ([docs] Update Astro dependencies - 2026-04-21):
1. Confirm all CI checks are passing for the head commit.
2. If all checks pass, mark the PR as ready for review (remove draft status).
3. If any checks are failing, investigate the failure and propose a fix.
