// inventory and guidelines. Key points:
// - Framework baseline is ~152 kB gzipped (Next.js + React + shared providers)
// - Heavy deps (Sentry, Supabase, Lexical) are lazy-loaded via dynamic import
// - Per-route budget: 200 kB gzipped, enforced by `pnpm test:bundle`
// - Framework baseline budget: 160 kB gzipped, checked by the same script
