## Reader Win
A Vercel launch checklist for output directory, canonical host, rewrites, analytics, and rollback.

## Evidence To Use
vercel.json, npm build output to docs, static markdown, and canonical URL rules.

## Thumbnail Direction
Deploy checklist over a preview URL frame with no account-specific project IDs.

## Writer Brief
Position Vercel as infrastructure, not the growth channel. Include the canonical-host warning.

## Call To Action
Review the Vercel launch checklist

## Public-Surface Rules
- Use real screenshots, generated public files, or dated public marketplace data as evidence.
- Do not include credentials, private account identifiers, unpublished analytics, or client-specific operational details.
- Treat marketplace downloads as listing-download evidence, not user-count proof.
