PR Summary

Medium Risk
PostCSS is on the CSS build path; the jump spans many patch releases including security-related source-map behavior, so visual/CSS output or tooling edge cases are worth a quick smoke test even though this is lockfile-only.

Overview
Updates the lockfile so postcss resolves from 8.4.31 to 8.5.25 (Dependabot). No application source changes—only yarn.lock.

PostCSS’s own dependencies in the lockfile move with it: nanoid to 3.3.17, picocolors to 1.1.1, and source-map-js to 1.2.1, with separate lock entries for nanoid where versions diverge.

The 8.5.x line adds bug fixes and hardening (e.g. tighter source-map loading and related security fixes noted in the release notes), which affects anything that runs PostCSS in the build/CSS pipeline.
