## Title

    Proposed fix: [Selenium/Chrome in Docker] 'session not created: ... DevToolsActivePort file doesn't exist' — Chrome crashes at start (small /dev/shm, or /dev/shm without exec on Docker Desktop WSL2)

## Body

    Recommended action: Run browser containers with --shm-size=2g (docker-selenium guidance); capture Chrome's own stderr/log to find the real crash reason; on Docker Desktop WSL2 check /dev/shm mount permissions; pin full image tags.
    
    Option: Give Chrome enough shared memory [evidence: official_recommended_action]
    Applies when: see problem
    Steps:
    1. docker run --shm-size=2g ...
    2. or compose shm_size: 2gb
    Expected: Chrome starts
