# Cap the Next.js build heap and page-data worker pool inside the Bun image the
# same way the node Dockerfile does (#10060/#11419/#7518). Without these knobs
# Next falls back to its defaults: worker pool = os.cpus()-1 (3 on the 4-vCPU
# GitHub runner) and an 8 GB V8 heap ceiling per process. 4+ V8 processes at
# multi-GB each blow past the 16 GB runner, the cgroup OOM killer SIGKILLs a
# build worker mid-compile, and buildx fails the step with `ResourceExhausted:
# ... cannot allocate memory` — every Bun image published on main since the -bun
# targets landed (#11709, #11039).
#
# The per-process peak is a MEASURED ~4.5 GB RSS (dmesg OOM-killer report,
# #7518), independent of NODE_OPTIONS — Turbopack is native/Rust and compiles
# outside the V8 heap — and it applies to the parent process too, so 2 page-data
# workers (3 processes × 4.5 GB ≈ 13.5 GB) do not fit the 12.288 GB (75%)
# budget either. Both images therefore default to OMNIROUTE_BUILD_WORKERS=2
# (1 page-data worker): 2 processes × 4.5 GB ≈ 9 GB fits with headroom (#11663).
# The default Turbopack path keeps the compile outside the V8 heap, but the
# guards must hold for the webpack fallback (OMNIROUTE_USE_TURBOPACK=0) too, so
# they are wired exactly like the node image.
#
# NODE_OPTIONS propagates to the spawned `next build` child and its workers
# (build-next-isolated.mjs → resolveNextBuildEnv spreads process.env), so the
# ceiling is per PROCESS, not per build.
