# Platform is forced via `docker build/run --platform linux/amd64` (see
# scripts/docker-test/{image,container}.mjs) rather than hardcoded here, to
# avoid BuildKit's FromPlatformFlagConstDisallowed lint warning.
#
# Ubuntu version MUST match `runs-on` in .github/workflows/nodejs.yml.
# GitHub silently redefines what "ubuntu-latest" means (last moved
# 22.04 → 24.04 in Jan 2025) — check that workflow whenever bumping this.

# NOTE: this always installs whatever apt's "stable" channel currently
# resolves to; CI's runner image ships a periodically-frozen Chrome snapshot,
# so exact version parity is not guaranteed (see justfile / SKILL.md caveat).
