# The NestJS backend for local development, in watch mode against the bind-mounted sources.
#
#   pnpm dev            # starts this, then runs apps/web natively on the host
#   pnpm dev:build      # rebuild the image after a dependency change
#   pnpm dev:down       # stop and remove the container
#
# Requires a root .env (copy .env.example and fill in the Supabase values).
#
# apps/web deliberately stays off this stack. A container reads bind-mounted files through
# the host boundary, which on Windows costs milliseconds per file — Vite pays that thousands
# of times per render, and it also gets no inotify events, so the watcher has to poll. The
# backend touches files rarely enough that neither matters to it.

      # because the backend resolves @languages-learner/* through those symlinks.
