/**
 * Storage adapter for editor-specific storage access.
 *
 * Purpose: Abstracts away editor-specific storage patterns.
 * This allows the codebase to be more generic and reusable across different editor implementations.
 *
 * Key responsibilities:
 * - Get extension storage from editor instance
 * - Get persistVeltMarks setting from storage
 * - Get editorId from storage
 *
 * Dependencies:
 * - @tiptap/core (ONLY place allowed to import Editor types for storage access)
 * - utils/console.ts (for logging)
