# Base from `deps` so we keep a single set of system libs (apt) + Playwright
# browser cache. A fresh `node:22-slim` + `npx playwright install-deps` would
# duplicate the same apt work (~40s) and can pull a different @playwright version
# (see build logs: runner npx → playwright@1.59 while lockfile may differ).
