PR Summary

Low Risk
Lockfile-only dependency bump; risk is mainly regression in CSS processing or stricter source-map behavior in build tooling, not runtime app logic changes.

Overview
Updates the lockfile so postcss resolves to 8.5.23 (from 8.4.31) for the postcss@^8.4.7 tree, along with refreshed transitive pins (nanoid, picocolors, source-map-js).

The newer postcss line includes security hardening around source-map loading (e.g. not loading maps without opts.from, tighter path restrictions; unsafeMap to opt out) plus parsing/CSS output fixes and XSS-related fixes from intermediate releases—no application source changes in this PR.
