Pull request overview

Updates the Playwright MCP server Kubernetes manifest examples to ensure the server binds to all interfaces so it’s reachable from outside the pod.

Changes:

• Add --host 0.0.0.0 to the args list in all three K8s manifest examples.
• Bump the Playwright MCP image tag from v0.0.54 to v0.0.59.
• Update the “Important” note to include the new required argument.

• The code block line-highlighting directive for playwright-restricted.yaml ({16-17}) no longer matches the lines being introduced/emphasized. After adding --host, --allowed-origins is now on later lines in the snippet, so the highlight range should be updated to point at the --allowed-origins lines instead of highlighting --allowed-hosts.

    - '0.0.0.0'
    - '--allowed-hosts'
    - '*'
    - '--allowed-origins'
    - 'example.com;trusted-domain.org'

• The line-highlighting directive for playwright-with-volume.yaml ({16-17,22-25,28-31}) is now out of sync after inserting --host. The first highlighted range currently points at --allowed-hosts rather than the output-related args; update the highlight ranges so they emphasize the intended --output-dir/save options and the volume/volumeMount sections.

    - '--allowed-hosts'
    - '*'
    - '--output-dir'
    - '/browser-output'
    - '--save-trace'
    - '--save-session'
