Approving. postcss is a direct build-time devDep (the root Gatsby CSS pipeline). 8.5.11 = nested-bracket parse perf fix; 8.5.12 = security fix for arbitrary file read via user-generated CSS, plus an opt-in opts.unsafeMap escape hatch. We only process trusted, developer-authored CSS at build time so real exposure is negligible, but it's a clean security patch within ^8.5.x. Safe.
