Same drift as the builder stage, in the paragraphs just below it. The
image exports OMNIROUTE_MEMORY_MB=1024 and derives NODE_OPTIONS from it,
but the guide reported 512 in three places, including the environment
variable table.
The "if unset, the launcher uses 512" line was misleading in both
readings: the image always sets the variable so that branch cannot fire
under Docker, and outside Docker the launcher calibrates from host RAM
rather than using a flat 512.
