⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: pnpm-lock.yaml

Progress: resolved 1, reused 0, downloaded 0, added 0
Progress: resolved 119, reused 0, downloaded 0, added 0
 ERR_PNPM_TRUST_DOWNGRADE  High-risk trust downgrade for "chokidar@4.0.3" (possible package takeover)

This error happened while installing the dependencies of sass@1.99.0

Trust checks are based solely on publish date, not semver. A package cannot be installed if any earlier-published version had stronger trust evidence. Earlier versions had provenance attestation, but this version has no trust evidence. A trust downgrade may indicate a supply chain incident.
