Prompt
You are in Cursor acting as a senior engineer preparing this app for launch. Do a focused launch-readiness pass. Do not refactor unrelated code. Inspect the homepage, pricing, onboarding, auth, sitemap, robots, metadata, social previews, accessibility basics, mobile layout, error states, security headers and environment variable usage. Give me a prioritized checklist first. Then implement only the safe, high-impact fixes after I approve.
