/*
 * Copy Note Text — Obsidian plugin
 * Adds a "copy" icon to the note's action bar (top-right, next to the reading
 * view and the more-options "..." menu). Clicking it instantly copies the
 * note's entire text to the clipboard.
 *
 * This file is the plain JavaScript build (CommonJS), ready to be used by
 * Obsidian without any compilation. The TypeScript source is in main.ts.
