Summary

• Import the runtime compiler from @unocss/core.
• Remove the directives transformer from published-site token compilation.
• Add a Worker bundle guard for createRequire-based loaders.
• Declare @unocss/core as a direct dependency.

Root cause

The broad unocss entry and directives transformer pulled a CommonJS createRequire-based css-tree loader into the Cloudflare Worker bundle.

Impact

Runtime utility CSS compilation remains available without shipping Node-only loader behavior to workerd.

Validation

• UnoCSS configuration tests passed.
• A fresh production build passed bundle integrity and Cloudflare Worker size checks.
• The combined v0.5.10 series passed 4,842 tests with 1 skipped, plus runtime and package smoke.

Release plan

Part 6 of 9 for v0.5.10. This PR intentionally excludes the separate SSR optimizer configuration fix.

Warning

Review limit reached

@andycamara, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 13 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
