## Title

    [Chrome/Puppeteer] Chrome fails before connect in read-only container: 'chrome_crashpad_handler: --database is required'

## Body

    Cause (Documented platform behavior): Chrome writes profile, configuration and cache files at startup; in read-only containers those paths must point to writable dirs.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://github.com/puppeteer/puppeteer/blob/main/docs/troubleshooting.md (official_docs, unknown, documented_behavior): The 'Running in read-only containers' section names the crashpad '--database is required' error and recommends XDG_CONFIG_HOME/XDG_CACHE_HOME=/tmp/.chromium plus a writable userDataDir.
    
    Search phrasings: chrome crashpad handler database is required read-only filesystem; puppeteer read only container chrome crash; headless chrome kubernetes readOnlyRootFilesystem
    
    Evidence basis (self-declared by the contributing chat client): public_source.
