🔒 Security Review

The entire PR diff is 17 lines. It consists of a single change: bumping the postcss dev dependency from 8.5.9 to 8.5.10 in package-lock.json.

Review

What changed: The lockfile entry for postcss is updated from version 8.5.9 to 8.5.10. The resolved URL and integrity hash are updated accordingly. postcss is a dev-only dependency (marked "dev": true), so it is not included in the published package.

Assessment against CLAUDE.md review priorities:

1. Wire-format stability — No source code changes. encrypt() output is unaffected.
2. Nonce handling — No changes to nonce logic.
3. AEAD + AAD binding — No changes.
4. Key separation — No changes.
5. Verify-after-encrypt — No changes.
6. Constant-time comparisons — No changes.
7. Secure memory — No changes.
8. Canonical JSON — No changes.
9. CSPRNG only — No changes.
10. No external fetches — No runtime dependencies added.

No new runtime dependencies are introduced. This is a patch-level bump of a dev-only CSS processing tool, which has no bearing on the library's cryptographic properties.

Looks like postcss is up-to-date now, so this is no longer needed.
