/**
 * @module Shared/RegisterGlobals
 * @description Imports Chart.js, D3.js, and Papa Parse as ES modules and registers them on globalThis.
 *
 * Dashboard modules access these libraries via `(globalThis as any).Chart`,
 * `(globalThis as any).d3`, and `(globalThis as any).Papa`. ES module side-effect
 * imports (`import 'chart.js/auto'`) do NOT set globals, so this module must be
 * imported before any dashboard module to ensure the globals are available at
 * module-evaluation time.
 *
 * @security No inline scripts — all library loading is programmatic via Vite bundling
 */
 
import { Chart } from 'chart.js/auto';

// Expose on globalThis so dashboard modules can access via (globalThis as any).Chart / .d3 / .Papa

// Optional Chart.js plugins must be imported explicitly by applications that
// need them. Do not dynamically import `chartjs-plugin-annotation` here:
// bundlers such as Vite/Rollup/Webpack will still try to resolve the module
// at build time and fail when the optional dependency is not installed.
//
// To enable annotations, import `chartjs-plugin-annotation` in the consuming
// entry point before creating charts that use annotation configuration.
