# Pinned Playwright release used to fetch a known-good, arch-native
# chrome-headless-shell on arm64. chrome-for-testing publishes no linux-arm64
# build, so arm64 used to fall back to Debian's *unpinned, rolling* `chromium`
# package — whose bookworm arm64 build SIGTRAPs at startup (exit 133), breaking
# every containerized render (issue #2039). Playwright ships a pinned
# linux-arm64 headless-shell (Google's build, not Debian's). Bump deliberately.
