# Build to populate dist/. The dist directory is excluded from the
# image by .dockerignore (build artefacts get rebuilt inside the
# container), so we have to compile here — `package.json:_moduleAliases`
# resolves `@shared/*` → `dist/*` at runtime, and without this step
# nodemon would crash on first load with "Cannot find module
# /app/dist/shared/error/app.error". nodemon still watches src/ for
# hot-reload; ts-node compiles changed files on-the-fly while dist/
# stays the source of truth for module-alias lookups.
