/**
 * Default export function that will be used by stencil global script,
 * which will be invoked before library loaded.
 *
 * This lean version only contains essential setup that ALL consumers need:
 * - Feature flag configuration from client globals
 * - Global slimmers (component lifecycle hooks)
 * - Typography injection
 * - Telemetry initialization (VegaEnvInfo + runtime metrics)
 * - CSP nonce head patch
 * - VegaModuleLoader on globalThis (for on-demand lazy loading of public API modules)
 * - Apply branding from client global (via VegaModuleLoader, zero static-import cost)
 *
 * The heavier vanilla-JS-only globalThis injections are handled separately
 * by vanillaJsGlobalSetup (only in `vega.esm.js`, the full browser entry).
 * Consumers who want a leaner bundle can use `vega-lean.esm.js` instead.
