…mium - Install chromium + fonts-freefont-ttf via apt instead of npx playwright install - Set PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1 and PLAYWRIGHT_CHROMIUM_EXECUTABLE_PATH - Expand init-docker.sh MCP patch to all architectures with --executable-path and --no-sandbox - Fix CI verify steps: chromium-browser → chromium (Debian Trixie binary name) - Update dockerfile.md to document system Chromium approach Eliminates 8+ minute browser re-downloads caused by @playwright/mcp@latest depending on alpha playwright-core versions that differ from build-time cache.

The chromium Debian package pulls in systemd, which creates systemd-network with GID 998. Use groupadd -f to exit successfully when the GID is already taken.
systemd (pulled by chromium) claims both GID 998 and 999. Use groupadd -f for both ping and docker groups.

What
Replace Playwright-managed browser downloads with Debian's system Chromium, using
--executable-pathto bypass Playwright's version-coupled browser management.Why
The image cached Chromium for
playwright@1.58.2(revision 1208) at build time, but@playwright/mcp@latestdepends onplaywright-core@1.60.0-alpha(revision 1217) at runtime — causing an 8+ minute browser re-download on every container start. This is structurally unfixable with version pinning because@playwright/mcpuses alpha Playwright builds that change nearly every release (43 of 63 releases used different versions).Changes
