library0.4.2jsnpmunverified

Visual migration framework for Claude Code — clone live pages to WordPress/Elementor HTML widgets or Shopify Liquid sections, validated and auto-corrected. Current stable v0.4.2 (MATURE). Released on npm under MIT license. Releases are irregular but stable. Key differentiators: mobile-first (iPhone 14 viewport), deterministic pipeline with 8 sub-skills, decision matrix 2×2 for delivery vs correction loop, cumulative HTML report with interactive slider, and machine-parseable memory cascade. Requires Node ≥20 and Claude Code installed.
