also applied the same policy file to the headless image. Tested this with a vibed up playwright script that connected to the headless image and took a screenshot of coupang.com

Note

Adds CJK/emoji fonts and shared Chromium managed policy (disabling translate/autofill/password manager) to both headful and headless images.

• Docker images:
  • Headful (images/chromium-headful/Dockerfile):
    • Install fontconfig, fonts-noto-cjk, fonts-noto-color-emoji, fonts-nanum; run fc-cache -f; minor cleanup with apt-get clean.
    • Copy shared Chromium managed policy to /etc/chromium/policies/managed/policy.json.
  • Headless (images/chromium-headless/image/Dockerfile):
    • Install fontconfig, fonts-noto-cjk, fonts-noto-color-emoji, fonts-nanum; run fc-cache -f.
    • Copy shared Chromium managed policy to /etc/chromium/policies/managed/policy.json.
• Chromium policies:
  • Add shared/chromium-policies/managed/policy.json with PasswordManagerEnabled, AutofillCreditCardEnabled, and TranslateEnabled set to false.
  • Remove legacy image-chromium/etc/chromium/policies/managed/autofill.json.

This PR fixes an issue where non-English characters were not rendering correctly and disables Chromium's translation popup.

These changes are applied to both the chromium-headful and chromium-headless images to ensure consistent behavior.

• Font Installation: Added CJK, emoji, and Nanum font packages to both Dockerfiles to ensure proper character rendering.
• Shared Chromium Policies:
  • Created a new shared policy at shared/chromium-policies/managed/policy.json to disable the password manager, credit card autofill, and the translation service.
  • Removed the old, duplicated autofill.json policy.
• Image Updates: Both headful and headless Dockerfiles were updated to install the new fonts and copy the shared policy file.

Looks like there is a conflict. But LGTM

[mesa-dot-dev]

Performed full review of e928eb1...bc7eb93

Analysis

1. No clear validation strategy for ensuring the centralized policy.json remains consistent and backward compatible when modified
2. Potential performance impact from adding comprehensive font support to both headful and headless images, which may increase image size and memory footprint
3. Lacks details on error handling or fallback mechanisms if font cache refresh after installation fails
4. No mention of compatibility testing across different operating systems/environments to ensure consistent font rendering
