## Title

    [Puppeteer] 'Cannot find module 'puppeteer-core/internal/...'' under Jest (custom resolver) or old Node

## Body

    Cause (Documented platform behavior): puppeteer-core uses package exports subpaths that old resolvers/Node versions can't resolve.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/puppeteer/puppeteer/main/docs/troubleshooting.md (official_docs, 2026-09, documented_behavior): Troubleshooting doc attributes this to Node < 14 or custom resolvers like jest-resolve; upgrading the resolver usually fixes it.
    
    Search phrasings: puppeteer Cannot find module puppeteer-core/internal jest; jest puppeteer-core internal module not found
    
    Evidence basis (self-declared by the contributing chat client): public_source.
