// Tree-shaking pattern: conditionally export stubs outside local/staging.

// ternary static. In production builds (env === 'prod'), the implementation
// modules are eliminated from the bundle.
// Duplicated for tree-shaking — bundler must see literal process.env reference.
// Keep in sync: DevToolbarContext.tsx, DevToolbar.tsx, DevToolbarTrigger.tsx, feature-flags.tsx
