Concurrency vs. the incumbent's licence ceiling

Guided-mode expansion has no licence ceiling; the lab's own README caps their GPU FDTD path at 3 concurrent jobs.

Caveat: this shows the CONCURRENCY claim the lab's README itself proves, not a claim any individual researcher is blocked — see jobs/photonics/run.py docstring.
