Code Review
This pull request adds a pnpm override to enforce postcss version 8.5.18 in package.json and updates the pnpm-lock.yaml file accordingly, which also upgrades nanoid to version 3.3.17. There are no review comments, so I have no feedback to provide.

The change is scoped to 2 files on the vulnerable path; it only tightens handling of untrusted input and leaves valid inputs unaffected.
This patch removes an exploit primitive — a code pattern that, while not independently exploitable today, could be chained with other weaknesses by automated exploit-development tooling. Proactive removal of such primitives raises the bar against increasingly capable automated attack tools.
