Summary by cubic

Upgrade postcss to 8.5.19 across the workspace to pick up security hardening (safer source map loading), bug fixes (stack overflow, prototype hijacking), and minor performance improvements. Updated the postcss catalog entry and refreshed pnpm-lock.yaml so related deps like postcss-import and postcss-load-config resolve against 8.5.19.
