Zustand Enforcement

Ban single-parens create<T>() -- must be create<T>()() for middleware type inference
Ban inline object selectors -- (s) => ({ a: s.a }) cause infinite re-renders, use useShallow
Ban localStorage/sessionStorage in store files -- use zustand persist middleware

Zustand client state only: theme, sidebar, selected tab, draft form data. Server data -> TanStack Query / Connect Query.
useShallow required for multi-value selectors (hook enforce).
Callback form required for set() (hook enforce).

Initial setup (install, config, verify): see SETUP.md.
