AI/MCP-Compatible Widget Schema & Semantic Metadata Layer for Elementor (to enable accurate AI-driven page building via Claude/other LLMs)

Describe the Problem When using AI models (Claude Code, Claude Design, or other LLM-based tools) connected to WordPress via the Elementor MCP integration, the AI is able to design visually excellent layouts conceptually, but fails to translate that design accurately into native Elementor widgets and structures. Specific issues encountered: • The AI cannot reliably discover, map, or configure Elementor's native widgets (both core and third-party, e.g., from addon packs) because there is no structured, machine-readable schema describing each widget's available settings, controls, nesting rules, and styling options. • Because of this gap, the AI defaults to inserting raw HTML/CSS blocks (via the HTML widget) instead of using proper Elementor widgets/sections/containers — meaning the final page is not truly "Elementor-native."
