Capture full-page before/after screenshots of two versions of a website and build a self-contained side-by-side HTML comparison report. Use this whenever someone wants to compare two sites or two versions of a site visually — re-themes, redesigns, replatforms, staging-vs-production checks, "screenshot these pages for me", "show me what changed", design QA before or after a launch, or building a visual record to share with stakeholders. Works for WooCommerce/WordPress and for any other stack, and handles bot-check interstitials, cookie banners, lazy-loaded images, and shell time limits that break naive screenshot scripts.
