# 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.

# ── Playwright Chromium OS dependencies ───────────────────────────────────────
# Vitest browser mode launches Playwright's own Chromium (no system Chrome).
# Only the OS libraries are baked into the image here (taken from the latest
# Playwright release at build time; `just build` refreshes them). The browser
# binary itself is downloaded inside the container by
# `npx playwright install chromium` (see scripts/docker-test/container.mjs),
# so it always matches the Playwright version in package-lock.json.

# Keep downloaded browsers in the cached node_modules volume so they survive
# `docker run --rm` and are reset together with node_modules.
