    # tmpfs ordering matters — the parent /app/.next must be mounted before
    # any sub-mounts. The entrypoint cp's image-baked templates into these
    # mounts at startup, then sed-substitutes, then chmod -R a-w.

    # mode=750: root-owned, group-readable. The entrypoint runs as root long
    # enough to copy templates, substitute placeholders, and chown the cache
    # directory to nextjs:nodejs (gid 1001). nodejs group members can read
    # the partially-substituted bundle during startup; nothing else on the
    # host can. After chmod a-w the served files are read-only for everyone.
