PR Summary

Low Risk
Lockfile-only patch bump of a CSS build-time parser with security fixes; no app logic changes.

Overview
Updates the frontend lockfile so the resolved postcss-selector-parser package moves from 6.1.2 to 6.1.4 (still a transitive dependency, not a direct package.json change).

That bump pulls in upstream 6.1.3 security work (CVE-2026-9358 / clone-walk handling) and 6.1.4 behavior around serializing selectors when non-node children are present. No application source files are modified—only package-lock.json.
