/**
 * Web entry point for @vnaidin/react-native-cryptocurrency-icons.
 *
 * This file is intentionally separate from the React Native entry (index.tsx)
 * and has NO dependency on react-native. It exports:
 *   - `getCryptoIconUrl(symbol)` — returns a URL string suitable for <img src>
 *   - `CryptoIcon` — a lightweight React web component (<img> with fallback avatar)
 *
 * For bundlers that support `new URL(..., import.meta.url)` (Vite, webpack 5+),
 * the PNG is resolved at build time and hashed into the output.
 *
 * The RN entry point (index.tsx / dist/index.js) is unaffected by this file.
