Resolves Dependabot alert #1: "PostCSS has XSS via unescaped </style> in CSS stringify output" (medium).\n\nPostCSS is a dev-only transitive dep of Vite/Tailwind and never reaches the production runtime, but pinning it removes the alert and ensures contributors build against the patched version. Adds a pnpm `overrides` entry; lockfile updated to 8.5.10.
