# apps/api — unified Hono/Bun API server
#
# Multi-stage build that runs from the monorepo root so the workspace
# packages (@mana/shared-hono, @mana/shared-storage, @mana/media-client,
# @mana/shared-logger) resolve via pnpm before being copied into a
# minimal runtime image.
#
# Build context MUST be the monorepo root, not apps/api/. The compose
# service uses `context: .` for this reason.

# ─── Runtime stage ─────────────────────────────────────────────
#
# Bun can run TypeScript directly without a compile step, so the
# runtime image just needs the workspace tree the builder produced.
# We copy /app wholesale rather than try to slice node_modules — the
# pnpm symlink farm is fragile and easy to break with selective copies.
