# `pnpm install` (below) installs every workspace's dependencies, including
# apps/web's `cypress` devDependency — this image never runs it, so skip its
# (large, Electron-bundled) binary download: saves build time/bandwidth and
# removes a network dependency on Cypress's CDN from every production build.
# The `cypress` npm *package* itself still ends up in `node_modules` (it's a
# real lockfile entry) and gets copied into `runtime` below — a deliberate
# tradeoff. Tried to prune it out too (`pnpm prune --prod`, then a full
# wipe-and-reinstall with `--prod`), but in this pnpm workspace both proved
# actively unsafe rather than just ineffective: `prune` doesn't cascade into
# sibling workspace projects' `node_modules` at all, and even a *scoped*
# `pnpm --filter web prune --prod` emptied out apps/api's entire
# `node_modules` as a side effect; the wipe-and-reinstall variant silently
# dropped argon2's compiled native binding (no postinstall re-run to rebuild
# it), which only surfaced as a crash *after* deploy
# (`Cannot find module '.../argon2.node'`) — not something to risk on the
# real production image for what's ~10MB of inert JS once the binary
# download above is already skipped.
