chore(deps): floor website postcss at 8.5.18#685
Merged
Conversation
postcss <=8.5.17 discloses arbitrary .map files through path traversal in the previous-source-map auto-loader (GHSA-r28c-9q8g-f849, high), fixed in 8.5.18. Transitive via @docusaurus/core; the docs-site lockfile pinned 8.5.14 and the existing >=8.5.10 floor still permitted it.

Summary
Clears a high-severity Dependabot advisory in the docs-site lockfile. Transitive through the Docusaurus toolchain; the Trivy filesystem scan is a required check, so it blocks non-docs PRs.
Closes #684
