 * ⚠️  IMPORTANT: This file contains the source code for the NOSTR_LOGIN_LITE library!
 * ⚠️  DO NOT edit lite/nostr-lite.js directly - it's auto-generated by this script!
 * ⚠️  To modify the library, edit this file (build.js) and run: node build.js
 *
 * This script builds the two-file architecture:
 * 1. nostr.bundle.js (official nostr-tools bundle - static file)
 * 2. nostr-lite.js (NOSTR_LOGIN_LITE library - built by this script)
 *
 * Features included:
 * - CSS-Only Theme System (no JSON duplication)
 * - Modal UI Component
 * - FloatingTab Component
 * - Extension Bridge
 * - Window.nostr facade
 * - Main NostrLite class with all functionality
